Our take on the Alpine CDE-HD137BT

by Zak Billmeier
Alpine

Why replace your factory radio?

Two good reasons - sound quality and cool features. A new car stereo offers power that's superior to most factory radios, along with more sophisticated tone controls. And most car stereos offer built-in or optional features that add safety and fun to life in your car, including inputs for your iPod or MP3 player, Bluetooth connectivity for hands-free cell phone calls, satellite radio or HD Radio reception, and connections for building an audio system in your car.

Alpine CDE-137BT

Bluetooth, evolved

Ever have that confusing conversation over Bluetooth where your caller keeps asking you to repeat what you're saying? Alpine gives you the tools you need need to end those annoying calls. First, you can mount the included microphone in a good spot in front of you so it'll have no problem picking up your voice. Next, the receiver lets you adjust the mic's gain to best match your speaking voice. You can also tweak the phone output and ring volume, so you won't go diving for the volume knob every time someone calls. And, last of all, this Alpine downloads up to a thousand names from your phonebook, and allows you to search by alphabet to find the number you want.

Stream music to your dash

If your phone or another device supports Bluetooth music streaming, you can beam your tunes and control playback with the CDE-HD137BT. You won't get full control this way, but you can perform some basic functions like track up and track down. Best of all, no wires are needed.

Built-in HD Radio™ and iTunes® tagging

Alpine's HD Radio tuner lets you tune in digital AM/FM broadcasts, significantly pumping up the sound quality. Participating FM stations sound about as good as a CD, while AM stations sound like traditional FM. If you've got subs in your system, you'll appreciate the bass HD Radio puts back in your favorite tunes. Plus while your iPod's connected and you've got an HD Radio station tuned in, you can "tag" songs you like for later purchase from the iTunes store.

Want to keep your steering wheel controls?

In most vehicles, you can use an adapter to connect your vehicle's steering wheel controls to this Alpine stereo. Connect a few wires, then program the adapter for your particular car and the CDE-HD137BT, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

    Preset EQ: You can select from 10 different EQ presets to get the best sound from all your sources. You can choose from Flat, Pops, Rock, News, Jazz, Electric Dance, Hip-Hop, Easy Listening, Country, or Classical. You can also select the User EQ preset to customize Bass, Mid, and Treble.

    3-Band Parametric Equalizer: If the Equalizer presets aren't enough for your listening taste, there's a 3-Band Parametric Equalizer (in User mode) you can adjust for a better sound response curve. Bass, Mid, & Treble can be adjusted in the 3-Band Parametric mode.

    • Treble Control:
      • Center Frequency: 7.5kHz, 10kHz (default), 12.5kHz, or 15kHz
      • Width Q: Wide 0.75 or Narrow 1.25
      • Level: -7 to +7 (+/-14dB in 2dB steps)
    • Midrange Control:
      • Center Frequency: 500Hz, 1.0kHz, 1.5kHz, or 2.5kHz
      • Width Q: Wide 0.75, Medium 1.0, Medium 1.25, or Narrow 1.5
      • Level: -7 to +7 (+/-14dB in 2dB steps)
    • Bass Control:
      • Center Frequency: 60Hz, 80Hz (default), 100Hz, or 120Hz
      • Width Q: Wide 0.5, Medium 1.0, Medium 1.5, or Narrow. 2.0
      • Level: -7 to +7 (+/-14dB in 2dB steps)

    Loudness: Loudness introduces a special low & high frequency emphasis at low listening levels to compensate for the ear's decreased sensitivity to bass and treble sound at low volume.

    Source Volume Level: The output level (+/-5dB) of each source can be individually adjusted. For example, if the Tuner level sounds lower than CD, its output can be adjusted without affecting the other sources.

    Interrupt Feature: When a device having the interrupt feature (such as a cellular telephone) is connected to the receiver, the audio signal will be automatically muted whenever the interrupt signal is received from the device. The supplied wiring harness contains a pink/black Interrupt lead that needs to be connected to the device's interrupt signal connection.

    Display Features

    Detachable Face: The unit features a single front loading CD face that detaches from the chassis to deter theft. The CD player comes supplied with a hard plastic face case to protect the detachable face when you have it off the chassis. A face-fixing screw is supplied for making the face non-detachable, if desired. An optional soft face case (142DFC1X, sold separately) can also be purchased for this unit.

    1-Line LCD Display: This unit is equipped with a 1-Line white-backlit LCD, so you can easily view AM/FM stations, CD-Text, & ID-3 tag information.

    Text Display: Text information, such as the disc name and the track name, will be displayed if playing a CD text compatible disc. It is also possible to display the folder name, the file name, & the tag information, while playing a MP3 disc or USB memory device.

    Text Scroll: This unit can scroll the disc & track names recorded on CD-Text disc, as well as the text information of MP3 files, folder names, and tags. There are two Text Scroll settings.

    • Auto: The CD text information, the information of folder and file names, and the tags are scrolled automatically.
    • Manual: The display is scrolled when a disc is loaded or when a track is changed.

    Auto Dimmer: This unit is equipped with an illumination lead; when the unit's dimmer mode is set to Auto and the illumination lead is connected to your vehicle's headlight circuit, the display and button illumination will dim to a fixed, preset level whenever the headlights are turned on. If preferred, you may choose the Manual dimmer mode setting, so the display and button illumination is dim at all times.

    Demo Mode: This unit has a demonstration feature for its display which can be turned On or Off in the menu.

    Remote Control

    Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input on the rear of the unit that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately). Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.

    Optional Wireless Remote: The Alpine CDE-HD137BT is wireless remote control ready. Simply add on the Alpine RUE-4202 IR remote (500RUE4202, sold separately) to make it even easier to control the head unit's functions.

    I was in need of a new receiver for my car and just needed something basic. After looking at different radios, features, etc I decided to get something I would be happy with. I had an Alpine years ago in another car so I was familiar with their quality. I must say I am very pleased with my purchase not only does it look good but it made my stock speakers come alive. Crutchfield rocks with fast shipping and they supply the kit and harness along with detailed instructions for installing. Thank you Alpine and Crutchfield!!
    Pros:
    Alpine quality Bluetooth HD Radio Looks great sounds even better
    Cons:
    It doesnt drive the car

    Awesome sound, easy controls although they are small buttons. Probably bad for a person with large finger tips. Most of my AM stations are received in HD. Reasonable Equalizer controls. I can adjust any input to my hearing pleasure. Overall great product. I have been purchasing stereo equipment from Crutchfield for some time. Always great service.
    Pros:
    Nice equalizer, Nice display and color scheme. Easy to program and use. Quality build.
    Cons:
    Few modications were needed in wiring harness. Not a perfect fit in wiring. Had to modify dash installation depth to be flush with climate controls.

    Great head unit with lots of features

    Written By Peterson, Tampa,FL. on Tuesday, March 12, 2013
    Crutchfield Customer Review (What's this?)
     
    I purchased this unit for my wife. I was looking to add an iphone connection to her car, but there was limited options for this year Mercedes, and the cost would be around $300. I considered other options and found the Alpine 137. It had the iphone/ipod usb connection which charges the unit, an auxillary input and she can play mp3's from the cd player. Installation was relatively simple with the dash wiring kit and antenna adapter Crutchfield included. I was able to purchase a steering wheel interface to make the factory wheel controls operate some of the functions on the Alpine unit. This head unit has a remote input jack on the rear as well as a mic jack for the supplied microphone for the hands free calling. The dash wiring kit was already to plug into the pre-outs on the radio and work with the existing Bose system. The sound quality is great and the iphone paired up perfectly with the radio. She can now stream music or take calls via bluetooth. The phone is a 4s so all the Siri functions work by voice command through the bluetooth. The radio controls can't scroll the menus in the phone via bluetooth, but it can when connected to the usb. We could not be happier with the unit and the functions. The unit and the interfaces I bought still cost less than the ipod adapter kit I was originally looking at, plus we gained a lot more. I looked around and did not find much better pricing than Crutchfield, especially with the free wiring kit,antenna adapter and free shipping.
    Pros:
    Bluetooth can stream audio and phone calls. Aux input. Very good sound quality. Steering wheel control interface capability.
    Cons:
    None that I can think of.

    Great Headunit

    Written By clduval, Farmington, NH on Friday, March 08, 2013
    Crutchfield Customer Review (What's this?)
     
    The receiver is awesome! I had a bit of difficulty during the install because the instructions did not specify that the install kit frame that is included, from Crutchfield, actually comes apart and the rear part goes in before anything else and the front part goes in last. The instructions only showed a single frame piece. After a quick call to Crutchfield, all was resolved. The actual receiver is awesome with all of its features. The hands free calling comes in as clear as a bell and the callers claim that it sounds like I am actually on the phone with them. The Bluetooth connectivity with my phone is great and the Pandora is a plus, even though I don't listen to Pandora much due to Sprint's 3G only coverage in the Northeast. One thing that did confuse me and required some reading, was determining how to change the radio station without scanning. This required going to menu and changing the option from scan to single or something like that. Other than that, I couldn't be any happier.
    Pros:
    The receiver works great and sounds great! HD stereo sounds awesome as does all other features. The price was the lowest I could find seeing as how the installation gear comes free with the purchase. Even the auction websites couldn't match the price with used parts.
    Cons:
    I only purchased this receiver because the CDE-133BT (I think that was the model number) became discontinued literally minutes before I bought it. I was willing to pay extra, and honestly, it doesn't bother me. As stated in the review, it was convoluted as to how to change the radio station one channel at a time without scanning. Pandora occasionally opens slowly, but it could be my poor internet connection. That is truly all that I have an issue with, otherwise, it's a great receiver.

    Another Great Alpine

    Crutchfield Customer Review (What's this?)
     
    This is a great choice and offers a little something for all your needs. Streaming audio through Bluetooth is smooth and sounds great. My HTC One X with Beats Audio sounds amazing streaming over BT or a directly connection. HD Radio is the future and offers another choice when you want good quality music without fighting with your phone. Pandora controls are great but quality is average. I never had any issues with Pandora streaming and controls through the main unit worked flawlessly. There is plenty of room to expand with three preamp outputs and they are clearly marked. Phone call quality is great. I have a 05 F150 Extended Cab. People can hear me clearly and without distortion at highway speeds. I positioned the mic on the top edge of the driver side pillar and it works perfectly.

    Love the BT Audio Streaming

    Crutchfield Customer Review (What's this?)
     
    I love this Receiver. I have installed several Head Units in my vehicles and usually when I buy a Jeep the first thing I do is upgrade the audio. I was really interested in BT Streaming. I commute daily to work and I like listening to my music, not the radio. I love the ability to connect my IPhone through BT. I have had zero problems with this head unit. The BT phone connection is a bonus, but not the reason that I bought it. It was really easy to set up and install. Crutchfield is amazing with the installation worksheets. Overall great purchase experience and I would recommend this product to anyone.
    Pros:

    HD137BT

    Crutchfield Customer Review (What's this?)
     
    Alpine hit it off with all the feature sets offered with this head-unit. Bluetooth works fine for calls but I haven't tested audio functionality with it. It sounds nice in the car I have it in, also has the factory Mach460 sound-system, make sure you cut the coaxial plugs off and use the standard audio feed from the head-unit unless you want it to sound flat. The built in EQ presets are mediocre, usually it sounds best with your own preset. To date this head unit is feature rich and has HD-audio while keeping the radio up to date with current trending technology. If you want something feature rich, go with this. It has everything you need.
    Pros:
    Parametric EQ settings, quality, sound. HU dims when dash lights come on.
    Cons:
    With the iPod classic it doesn't seem to memorize the playlist or artists you had selected when you turn the car off, I believe that's due to the application issue within the iPod itself rather the head unit, alpine needs to fix this for future head units as this problem existed in previous ones I've owned.

    Alpine CDE-HD137BT Awsome!

    Written By ECB, Lansing,MI on Tuesday, January 29, 2013
    Crutchfield Customer Review (What's this?)
     
    I installed this unit last weekend in my 2005 silverado extended cab P/U. The instruction I that came with this unit were kind of vague but the tech support from Crutchfields were a big help. My truck has the Bose system so I used the Crux SOOGM-15 interphase. The install would have been a breese but I got ahead of myself and installed the resistors in the harness because because the instructions said "hissing was possible" without adding the resistors. After I had the unit installed, the sound was horrible. I called Crutchfield and explained the problem and they recommended that I take the resistors out. After doing this, it sounded incredible. What an improvement over the factory deck. The only problem I'm having now is syncing my phone to the bluetooth.
    Pros:
    Sound Quality
    Cons:
    Bluetooth

    Bought this for my son's 1999 Nissan Sentra. He loves his radio; I offered to buy him new speakers but he say the quality is good enough with this radio in lieu of the old one.
    Pros:
    Reasonably priced, worth every penny. Bluetooth works fine, improved quality of sound of factory speakers. I had to assist him in cutting the plastic frame for the dash, but it he was able to install the radio by himslef without a problem.
    Cons:
    None so far.

    Spotty Bluetooth with Droid Razr Maxx

    Installation on Honda S2000 was straightforward. Sound is great, radio gets decent reception. Only bad news is the Bluetooth with my phone doesn't work reliably. Every few times I get in the car, the Alpine reports "No Unit" and I have to re-pair. Very annoying. Hopefully an Android update or new firmware from Alpine will fix this at some point.

    Alpine CDE-HD137BT

    Written By Anonymous, Bloomington, IL on Friday, January 18, 2013
     
    Installed in my '08 Lancer. Great head unit! I have an iPhone and discovered that with the update to iOS6 the AVRCP Bluetooth profile version supported on the iPhone is only 1.4 and this head unit only supports AVRCP 1.3 currently. I say currently because this unit supports firmware updates and would imagine updates should come somewhat soon (official Facebook post stating firmware update in the works.

    FYI the AVRCP profile allows the head unit audio controls like pause, play, next song, previous song, now playing song name. Without this profile support all song changes need to be made on the iPhone itself. A2DP profile still works so audio streams perfectly.
    Pros:
    *Great buttons *Great Bluetooth quality *Great Bluetooth mic (included) *Decent Equalizer *Ease of use
    Cons:
    *AVRCP 1.3 Support Only (iOS6 only supports 1.4) *No rear USB port *Audio settings can be slightly adjusted between sources but EQ settings are static across all sources (sucks when BT Audio EQ settings are great but then switching to HD Radio audio sounds hallow) *Remembering to click the back button to go backwards in the menu *Not a whole lot of control over settings (exception being the Equalizer, this may be a pro for those who like a quick setup and not a lot of configuration)

    Much better than my five year old Alpine! Can operate iPod from front USB while plugged in and running...huge upgrade rather than operating iPod through receiver. iPhone Bluetooth works great and was even surprised when I got back in started playing right where I left off...super simple...however my old Samsung phone with Bluetooth wouldn't pair up. Sound is great and now they have a mid's control along with bass and treble. Hooked up the Alpine power pack with this and was off!

    Good Alpine Product

    Written By aepuli, Frederick, MD on Thursday, January 17, 2013
    Crutchfield Customer Review (What's this?)
     
    Installed in a 2004 Toyota Matrix and am satisfied. Looks and sounds great as with Alpine products I've owned in the past. I prefer Alpine to other aftermarket HU manufacturer's because the quality is great, sound is great, and the appearance is clean and not too flashy (no gimicky animations or neon colors) - which makes it fit in well in an adult's car.

    My only complaints are that the unit start up can take a few moments after ignition, which was disconcerting at first, but I've gotten used to it. My phone (Samsung Galaxy S III) was not compatible with the Pandora bluetooth streaming, which after reviewing the manufacturer's documentation again I realized was not guaranteed. To my knowledge, Alpine does not maintain a list of compatible Android phones for this feature. Either way, I can still stream through bluetooth audio, just the controls are not available through the HU. Considering the great product, I would not change my purchase based on the bluetooth Pandora alone, and it still gets 5 stars from me.
    Pros:
    Appearance, Sound Quality, Functionality
    Cons:
    Boot Delay, Compatibility Issues with Pandora Bluetooth

    Love it. Installed very easy install. I use shrink tubing instead of tape. Cleaner and faster.
    Pros:
    Very impressed with the power and sound quality. Was concerned about that because the oem was a Bose with amp. Needed more features for road trips
    Cons:
    Humm still can't Bluetooth my blackberry yet. Keeps failing. Will figure that out today.

    Early Opinion

    Written By JcG, Niagara Falls ON on Monday, January 07, 2013
    Crutchfield Customer Review (What's this?)
     
    It appears that Alpine missed the remote command to advance music folders and radio presets. Seek will only the next station if finds and not user presets. The so called dimable display is more a joke that useful. I am disappointed Alpine did such a poor job with this feature. The "dim" is binary - two settings; OK and slightly less. pretty much useless IMO. Dimmable should mean controllable in an analogue way not some fixed guess by the designer.
    Pros:
    Easy to learn to navigate the menus. Good FM reception in bad areas.
    Cons:
    No advance through station presets or music folders. No useful display dimming. BlueTooth will not automatically reconnect if you walk away from the running car and return. You must manually reconnect or restart the vehicle. (bad). If vehicle power is disconnected most user settings are lost. Can't display clock and station frequency at the same time.

    Crutchfield Customer Review (What's this?)
     
    Great head unit! Powerful. My main reason I bought this product is the bluetooth capabilities. Great sound in the vehicle, and everyone I talk to has no issues with the sound on the other end, There are a few setting adjustments that I made to dial it in for the person on the other end. Easy to do.
    Pros:
    Quality built product. You can tell some thought was put into this product.
    Cons:
    none.

    First time buying an installing a new car stereo

    Written By Kent, Chicago on Thursday, December 27, 2012
    Crutchfield Customer Review (What's this?)
     
    It's a good stereo, and I feel like a made a good decision in buying it. But the installation process was not without its disappointments and one of my favorite features that I expected to be standard is just not present. Calling Alpine customer support for help and guidance was not a pleasant experience. I was treated like an annoyance.

    It was my first time installing a car stereo and so I had some learning to do, but I spent probably 20 hours installing, uninstalling, reinstalling, and doing research to learn everything I needed to learn. The manual says to have it installed by a dealer. But when you're purchasing the product nothing says "can only be installed by a professional".

    Worst of all the bluetooth microphone plugs into the BACK of the unit and this is easy to overlook during install. Would be nice if it were wireless or if there were much better instructions about how to install the microphone.
    Pros:
    --feature rich (bluetooth pandora, iPod, thumbdrive, HD radio, bluetooth calling, aux in all work) --sound quality delivers. Happy with the sound, even with the existing (factory) speakers. --good price point --the Alpine parts and manual were good but not great --the Crutchfield additional instructions for a Honda Civic were good but not great --I was looking to take a step up from the factory installed stereo to something that would allow bluetooth calling and an ipod plugin and this is
    Cons:
    --The stereo does not screw into the receiver assembly. It is held in place loosely by 4 metal prongs that simply exert pressure on it. Stereo can be easily stolen. --There are NO instructions on where to place the microphone either in the Alpine or the Crutchfield install guides. I found this a ridiculous oversight, especially for someone like me who had never done this before. --Both the Alpine and Crutchfield installation guides were too general about how to remove the panels.

    Crutchfield Customer Review (What's this?)
     
    I think it's a great product I am very happy with what I have received from Alpine. The sound quality is superior and it's a near perfect receiver.
    Pros:
    AUX and USB inserts. Pandora Bluetooth connection. HD Radio
    Cons:
    Their are a few but not many. The BT Pandora feature does not support iPhones. And it doesn't play WMA or ACC music files on CD's.

    This is a very cool head unit with Cd/MP3 player, USB input on front, Aux input on front, and easy Bluetooth.
    Pros:
    Easy Crutchfield install kit, Bluetooth works great and was easy to get going, HD radio has great sound too.
    Cons:
    HD radio range was disappointing. Fortunately, I have a Sirius receiver in line with antenna for long trips. Also display is hard to see in bright daylight.

    Crutchfield Customer Review (What's this?)
     
    After searching the web for a while trying to find a receiver to connect with auxiliary, Bluetooth and USB, I decided on this alpine. I wasn't looking for anything really high end seeing as how I have stock speakers in my Tacoma. The receiver install went really well with all of the extra stuff Crutchfield sent along with it (install took me about 2 hours as a first timer). Connectivity with my phone is spot on constantly with my Galaxy S3. Auxiliary is perfect and the USB i mainly use to charge my phone while I'm in the car. The option to use Pandora works pretty well for the most part but seems to have a long connecting time and a lag after skipping songs, if i want to use Pandora i usually just leave it on Bluetooth audio and change songs on my phone. The HD radio is a surprisingly nice addition that I didn't think I would ever use. My car is picking up all kinds of additional radio stations. The Microphone that comes with the receiver is very high quality, most people I talk to can't tell I'm in my car. The installation was kind of a pain but I'm writing that off to being inexperienced at this. Overall I'm very happy with picking this product and even happier that I went with Crutchfield instead of grabbing it off another retailer's website. I saved a ton of money and headaches by getting their free harnesses.

    Just bought it and installed at a big box store. looks good and sound is good compared to my old 2006 chrysler OEM stereo. I did pair it with my Android 4.1 phone & switched the source on the stereo to Bluetooth audio, even though the phone is paired successfully. I dont get audio all the time. Its a big hassle.

    I finally upgraded my 11 y/o factory unit and couldn't be happier. The sound quality is incredible even with the factory speakers.

    Pros:
    - bluetooth phone pairing is simple and works really well - Pandora control is nice - HD radio is sooooo much better
    Cons:
    - connecting the unit to my Samsung Galaxy Nexus (v4.1.1) isn't as easy as it should be

    Great product, great install

    Written By Bob Z, North Jersey on Sunday, September 16, 2012
    Crutchfield Customer Review (What's this?)
     
    I replaced the factory stereo in my 2005 BMW 325xi. I've been waiting for a single aftermarket unit with both HD radio and Bluetooth.

    HD Radio - I love it. I had HD radio in a previous car, courtesy of a JVC aftermarket stereo, so I wanted it in the car I'm driving now. The HD sound clarity is great, some commercial free channels. The problem with my previous JVC unit: poor reception about 20 miles away from NYC. This Alpine pulls in HD stations twice as far! And the Alpine finds more non-HD AM/FM stations than the factory BMW stereo. Bluetooth - It works great. Fast and easy pairing with iPhone 4s. Great sound in both directions. The wired mic was easy to route behind the glove box, and under trim around window to bring the mic out by the rear view mirror for perfect placement.

    Install: Easy. There are good instructions online that show how to pull apart the dash, route all the wires, etc. It's a step-by-step for a 2005 3 series. I also added an Axxess SWC which ties directly into the BMW Ibus. To make your install easy, buy the BMW wiring harness mating plug and preassemble everything. This will mean no cutting/soldering in the car. Remember to hook up the blue remote/power ant wire, as this also tells the BMW amp to turn on (no blue wire connection = no sound). To make the Axxess install without cutting wiries, connect the Axxess control wire to the Ibus (pin 7 in the BMW harness) in the connector.
    Pros:
    Complete set of functions. HD Radio. Bluetooth (compatible with iPhone 4s).
    Cons:
    No color adjustment to match car lighting color. A bit tough to fit into the old slot replacing the factory radio. Not a lot of room behind the radio to fit the wires.

    I was skeptical being a first time purchaser from Crutchfield, seen it through a Google search, fond alpine CDE-HD137BT vary nice unit a lot of capabilities. I called them for advice about hooking-up unit and they directed to select the right free hookup parts. And parts to disassemble my old unit-radio Anyway have little money, and I'm no 12volt electrical car mechanic and technician was very helpful the Crutchfield website took my cars info and let me know if system will work. Ok ordered unit when radio arrived with installation instructions that came with, go to hook-up, and needed help , called by cell in car for help, and right on the money wire by wire this took may be 30 minute at Crutchfield expense, How can you not want to recommend the team of Crutchfield with absolutely the best service and friendly too boot.

    Crutchfield Customer Review (What's this?)
     
    I was looking at this and a comparable Kenwood. I went to a local retailer to play with them and I couldn't work the Kenwood very easily, however I could work the Alpine very easily. Speaking with a few people the Alpine got way better reviews than Kenwood. I have to say, while it isn't as pretty as the Kenwood, it just works. Honestly, I want something that works first, style points are second. It does what I need it to do and once it is set up all you have to do is enjoy it! Like I said earlier, it just works. Good choice. It sounds great in my 4 speaker system and easy to use while driving. Alpine got a lot of great reviews from other installers and other users, count me in that group too....one note, pandora integration doesn't work on iPhone, you just play pandora through the Bluetooth audio.
    Pros:
    Sounds great, works with iPhone, crutchfield tech support was awesome. Easy to work, HD radio is great. Clear display, front USB and aux jack. BT phone is cool
    Cons:
    Standard 1line display, no rear USB or aux ports. Pandora on iPhone does NOT integrate with the radio. Preset buttons are small. Owners manual is on cd.

    Everything I hoped for

    Crutchfield Customer Review (What's this?)
     
    This unit does everything I hoped for when I ordered it. Great upgrade over the factory stereo in my 02 Ford Ranger standard cab. I kept the factory speakers, so I may not be getting the best sound this unit has to offer. A few minutes of reading the brief manual and some experimentation, and I'm loving the iPod connectivity, HD radio, and hands free calling with Bluetooth.
    Pros:
    Great iPod connectivity, HD stations sound great, excellent Bluetooth phone connectivity.
    Cons:
    Wish the display could be set to marquee to scroll station (or track in iPod mode), artist, and song. Seems I have to pick only one of these at a time.

    The sound quality is great and the integration with my old ipod is excellent. I was a bit disappointed in the Android integration, not only does it read the Android via USB the bluetooth streaming is very rudimentary with no music information. If this is a limitation of Android or Bluetooth then I would like to see Alpine make an App for Android to better integrate.
    Pros:
    Great sound quality, Great Ipod integration, Lots of Options, HS Radio Sounds Great
    Cons:
    Android integration is very much lacking.

    I upgraded my previous Alpine receiver to this one for the built in bluetooth. I've been using it with my Droid RAZR for a few weeks now, and it's worked flawlessly. Audio streaming is great, and the phone paired easily. The sound on my end is great, and everyone I've talked to said the sound quality was good on their end as well. Installation took about an hour on my Nissan Xterra, and was very simple with the supplied wiring harness and installation kit. Highly recommend.
    Pros:
    Good sound quality from the radio, streaming, and bluetooth.
    Cons:
    None so far.
