Notes:
  • You are able to keep your vehicle's factory installed Navigation, Satellite Radio, CD-changer, RSE (rear entertainment system), USB port, and/or Aux input.
  • The USA Spec BT45-INF is not compatible if any of the above vehicle's factory radio contains an "iPod/Menu" button.

Bluetooth Pairing: The USA Spec BT45-INF can only be paired and connected to one Bluetooth device at a time. Its compatible with most Bluetooth-enabled mobile devices such as Apple iPod touch/iPhone/iPad, Android smartphone/tablet, Blackberry, Windows phone, and more.

Note: 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 USA Spec BT45-INF.

Bluetooth Hands-Free Communication (HFP): The USA Spec BT45-INF supports Bluetooth Profile HFP for hands-free communication from your Bluetooth enabled mobile phone, so you can take (answer/end) phone calls through your vehicle's factory radio.

  • Answering a Phone Call: When there is an incoming call, your factory stereo's music will be muted and an audible ring-tone will be heard through your vehicle speakers. You can even have the BT45-INF announce the caller's phone number through your sound system; and for most text-capable radios if you miss the announcement, you can view the caller's phone number on your factory radio's display. To answer the call, simply press the Seek/Tune or CH+ button on your factory radio or steering wheel control. To end or reject a call, press the Seek/Tune or CH- button on your factory radio or steering wheel control.
  • Dialing a Phone Number: In order to dial a phone number, you will still need to use your Bluetooth-enabled mobile phone; you cannot dial a number from the factory radio. Once you've dialed a number from your mobile phone, then the call will be automatically transferred to the BT45-INF and your factory stereo system.
  • External Microphone: The USA Spec BT45-INF includes an external microphone to carry on your side of the conversation, while the caller's voice will be heard through your vehicle's speakers. The external microphone provides better performance in noisy environments than the integrated microphone found in many factory or aftermarket head units. The microphone is fitted with a 16' cable terminated by a 3.5mm connector that connects to the BT45-INF module; it measures 0.9375" (w) x 0.6875" (h) x 1.625" (d). The microphone has a self-adhesive backing to mount it to your vehicle's driver-side pillar, head-liner trim, or dash (do not mount it to the windshield.

Bluetooth Audio Streaming (A2DP/AVRCP): The BT45-INF supports Bluetooth Profiles A2DP and AVRCP for wireless audio streaming from a Bluetooth-enabled device that can also be controlled from the buttons on your vehicle's factory radio or steering wheel; in some cases you can also view song/artist information on your factory radio's display.

  • Wireless Music Streaming: You can stream music stored on your Bluetooth enabled device or stream music apps (such as Pandora, SiriusXM Radio, iHeartRadio, etc.) that are playing on your Bluetooth device to your vehicle's sound system (all speakers will play).
  • Music Control: You can control Play/Pause and Previous/Next Track functions from your vehicle's factory radio or steering wheel controls (other control functions will have to be done from your Bluetooth enabled device). You can control the volume of the music being streamed via your factory radio and steering wheel controls, or the Bluetooth device.
  • Song/Artist Information: In many cases, you can view artist, album, and song title information on your factory radio's display. In order to view song/artist information on your factory radio's display, your factory radio and your Bluetooth-enabled device must meet the following requirements:
    • Your factory radio must have a "SAT" button or "Radio" & "CAT" buttons; a satellite radio does not need to be activated, nor does the satellite radio tuner need to be present.
    • If you are using a Bluetooth-enabled Apple iPod touch/iPhone/iPad, then it must be running iOS 6 or higher. If you are using a Bluetooth-enabled Android smartphone/tablet, then it must be running Ice Cream Sandwich (4.0) or higher operating system.
    • Your device's Bluetooth AVRCP profiles must be 1.4 or higher.

Auxiliary Input: In addition to wireless Bluetooth connectivity, the USA Spec BT45-INF is fitted with an auxiliary audio input (3.5mm) for connection of practically any portable audio device with a headphone jack output or analog audio output.

USB Charging Port: The USA Spec BT45-INF features a USB (type-A) port to charge your smartphone or other portable audio device in your vehicle. Because the BT45-INF is a hide-away device, you'll want to purchase a USB extension cable (sold separately) to make the unit's USB charging port accessible. The USB charging port is rated at 5V/2.1A.

Note: This USB port is for charging only; it does not support music streaming.

Dip Switches: There are 4 dip switches that will need to be configured to match the type of factory radio you have; "SAT" button or "Radio" & "CAT" button.

Installation: The USA Spec BT45-INF installs either under the dash or in the trunk (based on type of vehicle and where the XM Satellite Radio tuner is located).

Concerns with battery drain reported in the reviews. Were those simply lemons or it's a wide spread issue?

No issues for the past year I've had it with battery drainage. - 2007 G35 Coupe 6MT

I have had mine installed for over a year. No issues. I love it

I had no issues thus far. No drain
[ ALONZO  Oct 29, 2018 ]

I was concerned about that too, but I have had the BT45-INFI installed for several months and I haven't had any issues with my battery.

Had this in my car for over a year, no battery drain issues at all.

Q
Can I use the built in Bluetooth for calls but this device for music? I'm asking because I don't want to have to route the mic for this device through my car. I have an 06 g35 sedan with Bose and sat.
[ Ry  Aug 19, 2018 ]

A
I use the bluetooth from an android phone connected to this device for media player audio, while using a separate bluetooth headset connected to the android device for phone call audio, and they work well together. I do not have the mic attached.
[ Peter  Aug 20, 2018 ]
A
yes the default blutooth in the car still works.
[ OMAR  Aug 20, 2018 ]
A
I have seen this answered in the positive. But I'm not sure where. You have to have SAT mode turned on for the Bluetooth AND/OR music to work. May I suggest USA Tech support in CA cuz I don't want to mislead? The mic does work great. Ran under rear seat, along bottom door trim front and rear up side trim where the cabin air filter is. Up A pillar under roof liner. I watched my installer and he took about 15 minutes to install and reinstall all the trim - came out good - it helps if you have some confidence (I didn't). Best wishes
[ Neil  Aug 20, 2018 ]
A
Yes I choose not to route the mic and I have my iPhone set to both the BT-45 and the in car Bluetooth so when a call comes in I just have to select what device I want to take the call on.
[ Bryan  Aug 20, 2018 ]
A
Yes. That's how I do it. You can turn off the call function from your phone Bluetooth settings for this device. 07 M45.
[ TRAVIS  Aug 20, 2018 ]
Q
Will this work in a 2010 g37 coupe...I don't have navigation....or bluetooth....and really want to keep my factory set up and just add bluetooth?
[ Brian  Mar 25, 2018 ]
1 answer
A
You must have satellite radio to use this product. If you have one it will most likely be located in the trunk under the rear deck cover. Sorry, I installed this in a 2007 M35 with navigation and satellite radio. Product works great if you can use it though.

Can I still use sat radio? 05 infiniti fx with bose

I don't expect this part to work in that vehicle, but the BT45-NIS might work: http://www.crutchfield.com/p_581BT45NIS/item.html I recommend contacting an advisor on 1-800-324-9695 to check your options. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101

I have an 07 M45 and sat works fine. It'll switch between Bluetooth and satellite.
[ TRAVIS  Feb 05, 2018 ]
Q
Should I disconnect the car battery before installing this product into my 2006 Infiniti G35 Sedan, so like the airbags don't come out when I am removing the car radio?
[ Bryce  May 18, 2017 ]
2 answers
A
Yes it would be preferable
[ Oren  May 19, 2017 ]
A
I didn't, however I did not have to remove the radio. All I had to do was install the unit in the trunk and connect into factory satellite radio harness. It was literally a 5 min install. I used Velcro to hold it to truck interior.
