Big two-line display and simple controls

It's like getting twice the Alpine for your dash — the CDE-W235BT CD receiver fills your vehicle's double-DIN (4" tall") opening, giving you an easy-to-read two-line display and easy-to-reach controls. You'll also enjoy that legendary Alpine sound quality, and a stereo that looks pretty handsome in your dash.

Stream music, talk hands-free

The CDE-W235BT lets you keep your hands on the wheel when a call comes in, and ensures you and your caller make a clear connection. Once you mount the included microphone in a good spot, you can adjust the mic's gain to best match your speaking voice. You can also tweak the phone output and ring volume ahead of time, so you won't go diving for the volume knob every time someone calls.

When a call comes in, you'll see your caller's name and phone number on the two-line display. You can answer the call by tapping the phone button on the front panel, or set up the receiver to answer all calls automatically. You can see some useful phone info on the screen, too, like a signal strength indicator and even an alert when a text message comes in.

Don't forget your iPhone

Your iPhone is the key to a seemingly never-ending supply of music. First, you can dive into all the tunes in your iTunes® library using the CDE-W235BT's controls. You can also play the audio from several popular Internet radio apps, meaning you'll never run out of music, no matter how long your journey may be.

Want to keep your steering wheel controls?

In most cars, you'll need an adapter to retain those controls with this car stereo. Connect a few wires, then program the adapter for your particular car and radio, and you'll retain the convenience of your steering wheel controls. You'll see the adapters that work with your vehicle when you add this receiver to your cart.

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.

    Display Features

    2-Line LCD Display: This unit is equipped with a 2-line white-backlit LCD, so you can easily view AM/FM stations, CD-Text, & ID-3/WMA 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/WMA 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/WMA 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.

    2-DIN Chassis: The Alpine CDE-W235BT has a 2-DIN chassis (also known as Double DIN), and will fit in many vehicles with a large dash opening. The unit can be ISO-mounted using factory brackets, or Euro-mounted using the supplied mounting sleeve. As always, please consult Crutchfield's Outfit My Car to verify fit with your vehicle.

    Disc Playback

    Disc Compatibility: The unit features a single disc player that will playback CD-Audio, CD-Text, and finalized CD-R/CD-RW audio discs.

    MP3/WMA Playback: This unit can play CD-R and CD-RW discs containing MP3/WMA audio files recorded using the ISO 9660 Level 1 or Level 2 formats. MP3 files with bit rates from 8-320 kbps are supported; WMA files with bit rates from 32-192 kbps are supported. Up to a maximum of 255 folders & a maximum 510 files can be read from one disc. ID3 tags (v1/v2) and WMA tags are supported; track title, artist name, and album name can be displayed.

    Note: The head unit does not support AAC file playback.

    Text/File/Folder Quick Search: When you are playing a disc with CD Text or ID3/WMA tags, you can easily search for a track, file, or folder by its title. Once you have activated the search mode, you can use the rotary encoder to quickly scan through the titles to locate the desired track. For discs without CD Text or ID3/WMA tags, searches are made using the track numbers associated with each song.

    Playback Modes: The Alpine CDE-W235BT offers Repeat and Random playback modes.

    • Repeat: Repeat Play (repeats playback of current track/file), Folder Repeat (repeats only files in current folder).
    • Random: Random Play (all tracks/files on disc are played in random order), Folder Random (only files in current folder are played back in random order).

    Off Insert/Eject: A CD disc can be inserted or ejected with the power off. When a disc is inserted with the power off, the unit will automatically power up and begin playback.

    Auto Reload: When a CD is ejected and left sticking out of the CD slot for 20 seconds, the unit automatically reloads the CD to protect if from damage.

    Angle Mounting: For proper CD playback, Alpine recommends mounting the CDE-W235BT no more that 35° above horizontal.

    Built-in Bluetooth

    Bluetooth Plus (powered by Parrot): The Alpine CDE-W235BT features built-in Bluetooth technology (v3.0), powered by Parrot. Parrot is the global leader in wireless devices for mobile phones, for expanded compatibility for many Bluetooth wireless technology enabled cell phones. The head unit's built-in Bluetooth allows you to make and receive phone calls wirelessly through the receiver; as well as stream music wirelessly from your smartphone to the head unit.

    Bluetooth Profiles: In order to use Bluetooth wireless technology, your phone must also be Bluetooth compatible and be able to interpret certain profiles. This unit is compatible with the following Bluetooth Profiles:

    • Hands-Free Communication: HFP (Hands Free Profile), HSP (Head Set Profile), OPP (Object Push Profile), PBAB (Phone Book Access Profile).
    • Audio Streaming: A2DP (Advanced Audio Distribution Profile), AVRCP (Audio/Video Remote Control Profile).

    Pairing: The Alpine CDE-W235BT can be paired to up to three Bluetooth enabled mobile devices (only one device can be used at a time). Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Alpine CDE-W235BT. Parrot software updates provide support for future phones.

    External Microphone with Noise Cancellation: The included external microphone (with visor-clip) allows you to speak to the other party on the telephone call hands-free, while the other party's voice is played through your car stereo speakers. The external microphone is tuned and engineered to reduce noise interference and feedback. This allows optimal placement in your car, for the best possible sound quality. You can adjust the microphone's volume level; and even mute the microphone, so your voice will not be heard by the caller. The external microphone measures 0.5625" (diameter) x 1.625" (deep); and features an attached 13' cable terminated by a right-angle male 3.5mm connector.

    Receiving Calls: The Alpine CDE-W235BT provides a couple ways to answer your phone calls without picking up your mobile phone. Incoming calls are announced by a caller ring tone through your vehicle's speakers (music will be muted) & a Caller ID message across your Alpine head unit's display.

    • Manual Answer: Manually answer an incoming call by pressing the "Phone" button on your Alpine head unit.
    • Automatic Answer: Set the Alpine head unit to answer the incoming call automatically; when a call is received, it is answered automatically after approximately 5 seconds.
    • Call Waiting: If a second call is received during a current call, you can have the first caller wait momentarily while you take the second call. When you are finished with one call, you can switch to the other.

    Placing Calls: The Alpine CDE-W235BT provides a variety of functions for placing a phone call without using your mobile phone. The Alpine CDE-W235BT features full phone book access, call history, voice tag dialing, and redial with compatible phones.

    • Voice Dialing: If you have a voice-dial capable phone, you can dial a phone contact by simply speaking the name of your contact.
    • Phonebook (with ABC search): Up to 1,000 entries (5 telephone numbers for each name) can be downloaded from your compatible mobile phone. You can select the first 3 call letters (ABC) to search for a desired name in your phonebook.
    • Preset Dialing: You can assign phone numbers that you dial frequently to presets (1-6) for quick recall. You can assign up to six frequently called phone numbers. A total of 18 phone numbers can be stored in the preset memory (6 numbers for each mobile phone paired).
    • Call History: The 80 previously dialed, received, or missed numbers can be retrieved and dialed from memory.

    Call Switch: This function allows you to initiate the transfer of audio between your mobile phone and your car's speakers.

    Text Message Alert: The CDE-W235BT can give you a notification on the display with a blinking mail icon indicator for 30 seconds while receiving a text message on your Bluetooth-enabled phone. The mail icon indicator will remain on if there is an unread message on a connected mobile phone. You must still read or create a text message from your mobile smartphone.

    Audio Streaming: The Alpine CDE-W235BT can stream music from you Bluetooth A2DP/AVRCP mobile device. Not only can it control & stream your music through Bluetooth, it can process your music using its built-in DSP Sound Expansion to ensure you get the best sound. Basic playback functions include - Play, Pause, & Skip (Previous/Next). The head unit will also display your stored music's song information; such as Artist name & Song/Album title. The CDE-W235BT also supports audio streaming of music apps on your Bluetooth-enabled smartphone, but without control or metadata. You will continue to use your Bluetooth enabled smartphone to view and control streaming music apps. When an incoming call or outgoing call is in progress from your Bluetooth enabled mobile phone, audio streaming will be paused so you can take your call. Once the call is finished, your streaming music will resume.

    Note: Bluetooth Firmware Update v01.27.00 is required for Bluetooth control and song information display from an Apple iOS 6.0+ device.

    Bluetooth Sound Quality Adjustments: You can customize the sound of your Bluetooth hands-free experience to fit your own preferences. You can adjust the CDE-W235BT's mic gain, phone output, & ring tone volume. If that's not enough, there are 5 sound quality settings to choose from to get the balance just right for you. This flexibility will make your phone calls a pleasurable experience.

    • Volume Adjustments: You can emphasize or weaken the volume level of phone call, the ring tone, and the microphone input to fit your own preference. The Phone Talk Level, Ring Tone, & Mic Gain are all adjustable between -5 to + 5 dB.
    • Sound Types: This unit provides 5 methods to improve the sound quality of your calls. You can choose the type according to your own preference - Type 1 (standard mode), Type 2 (enhances noise reduction), Type 3 (enhances echo-cancellation), Type 4 (enhances both noise reduction & echo cancellation), & Type 5 (weakens both noise reduction & echo-cancellation).

    Speaker Output: You can select which car speaker outputs the audio from your Bluetooth-enabled mobile phone/device.

    • All: The audio will be output from all of the speakers in the car
    • F-L: The sound is only output from the front left speaker.

    The ability to retain steering wheel controls with aftermarket receivers will be determined by the receiver you are using and the vehicle you have.

    I forwarded your question to an Advisor and they responded with the following: You will need to use the PAC MS-FRD1 Ford Sync Radio Replacement interface (item # 541MSFRD1) in order to retain the sync functionality of your vehicle. In addition the PAC SWI-RC Steering Wheel Radio Control Interface (item # 541SWIRC) will be needed to keep the steering wheel controls. When used together you can control the Sync via the steering wheel controls. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.

There are also a number of functions on the unit to control the iOS device, much like the iOS device itself.

    what is ESC on the Alpine radio and how does it work???
    [ Larry  Apr 04, 2014 ]
    2 answers
    Larry, I believe the ESC button stands for 'escape'. Whatever mode you are in, ie; time set, fader, etc, by hitting the escape key it allows you to 'start over'. It will return to your original screen for a 'do over'. The ESC key also acts as a 'hang-up' to terminate a phone call. I hope this helps you some. This is how I have been using the ESC key. Good Luck, Brian R
    [ BRIAN  Apr 05, 2014 ]
    As far as I can tell, it serves mostly as a back button. Most notably when when searching through files or setting up your bluetooth settings. Holding the ESC button for an extended period will take you back to the home screen. Hope this helps.
