I see that GM is offering Bluetooth connectivity on their 2009 Trailvoys (TrailBlazer, Envoy, 9-7x). I'm assuming that this is a new functionality that was added to the OnStar module. Does anyone know more about this? It would be cool if you could purchase an 09 OnStar Module and install it an 05-08. I'd really like Bluetooth connectivity in my 06 9-7x.
I just recently purchased a 2009 trailblazer and linked my iphone 5s with the bluetooth thru the radio and when I place a call the connection is fantastic, however when someone calls me, I can barely hear them, how do I make this connection louder?
I recently upgraded to a factory navigation unit and I also wanted Bluetooth. I found isimple connect on eBay and works great has a T harness for the back of the factory radio. And connects to a module for Bluetooth and 3.5mm jack and a USB port. Has 3 total inputs, I just put them in the center console. Can take phone calls streaming etc. just have to put up the mic. I put it inside the overhead console.
