Need for car with factory equipment
Gerardo o s S on Nov 28, 2016
Recently purchased a 2006 Yukon and want the ability to talk over Bluetooth and listen to internet radio or music from my portable devices over the factory radio. I will post a review after receiving the product and installing. My Yukon has the 6 disc factory radio, factory satellite radio, OnStar, and the rear entertainment package.
Jonathan R on Feb 16, 2015
I wanted to keep my factory radio in my 2006 Hummer H2. This seemed like the only product that would allow me to upgrade to "modern" blue tooth, hands free technology in my truck, without having to change out everything.
Ken P on Jul 10, 2016
The 2006 Hummer H2 w/ navigation offers no audio input options (line in) or Bluetooth capabilities. To enjoy the music without removing the factory radio (keeping it original) this seems like the most cost effective-easiest choice.

Will this work on my 2003 Suburban with the Bose system?
richie on Aug 7, 2014
Best Answer: As long as your system has/supports Satellite radio, the ISGM655 requires your radio to have a 'Band' or 'XM' button to function.

Will this system play on all the speakers with factory Bose in chevy silverado? crutch field has a bluetooth for the factory radio but it only plays on the front speakers.
A shopper on Sep 1, 2015
Best Answer: I installed this kit in my 2006 Yukon XL with factory head unit, factory Bose speakers, OnStar, and Rear Entertainment package. This unit plays Bluetooth audio over all my speakers. I have also had very good luck with call quality when using the Bluetooth for a conversation.

Best Answer: This is a great product. It took me about 2 hours to install everything correctly. I haven't had any problems with this product. I have been using it for about 5 months in my 2004 gmc yukon. No issues. Great product.

I have a 2007 Buick Lacrosse and OnStar is not activated, Does this work without OnStar?
Jane F on Jul 19, 2016
Best Answer: Hello,

I have an 06 with onstar and onstar is not activated either. It works just fine- the only thing is if you have xm satellite radio that will no longer work unless you buy an adapter. Thanks

I have a windows phone that supports Bluetooth, Will this support windows HTC phone via Bluetooth?
A shopper on Mar 29, 2016
Best Answer: I cannot speak to the HTC, but I have tried using this with a Nokia Lumina Windows phone. It works fine for call Audio, but it will not stream Media audio. This seems to be an issue with the windows phones because media audio and call audio both work fine with my Galaxy Note 4.

Will I have to buy something extra for this ? What is "AVRCP " ?
Control your media from stereo or steering wheel using Bluetooth Wireless Audio Control (AVRCP)
Colin C on Oct 11, 2015
Best Answer: Hello,

It appears that none of our customers have answered your question, so we will; Assuming a compatible vehicle, no other parts are required.

A2DP: Advanced Audio Distribution Profile allows high quality audio to be streamed from an audio device to the car stereo and have control over that stream.

Will this work in a Saab 93 linear sedan?
Rob F on Feb 22, 2015
Best Answer: Hello Rob,

Unfortunately, your vehicle is not listed in the compatibility list. You didn't provide us with a YEAR, so we had to check every possible year of the Make/Model, but came up blank. Moreover, no alternate solution was offered, link below.
