Attached below are pictures of both my current stereo system and the one I want to replace it with. I currently have to use an FM transmitter for music and it just kills the audio experience. So I am wanting to replace it with the Navi OEM that is also pictured below. Firstly, I want to make sure that I am able to put the system in properly and that it works with my car (2007 Cadillac STS 3.6L). My main reason for wanting to switch is because the Navi has Bluetooth. Would that Bluetooth allow me to play my music from my phone through the stereo? Also, I have been watching some videos about it and saw where people had some issues with the Bluetooth, clock, and navigation working. Most videos said I would need a GPS antenna. Would the onstar antenna that is already on the top of my car work? Also, with this stereo would I still be able to go in and edit my drivers settings? I appreciate anyone who read this. And I will be extremely grateful for any help. If you need anymore information about the car just ask. Thanks again!

These units were designed before Bluetooth music was popular. The only Bluetooth function you get is phone. You would also need to add a GPS antenna. And to add a VSS (vehicle speed sensor) signal I believe. It is not plug and play.

The above pic. is for the nav. unit you are wanting to go to. Notice there are 4 plugs in a row. Additionally, the pink coax is for the GPS antenna and in the glob of black tarry material is the old fashioned music signal antenna (am, fm). The blue connector at the edge of the tar is not used when installed.
I BELIEVE your radio has only 2 connectors instead of 4 and the same music signal antenna. No GPS antenna. Some of those extra wires connect to a totally different amplifier located in the trunk on the left sidewall. Also the radio head unit interfaces with the car computers and is itself a computer that controls all of the personalization adjustments and sounds for the car - even down to the "click" of the turn signal (comes out of one of the front speakers). I highly recomend not starting this even if you are very mechanically inclined. It has been done before, but not by many. It always involves near complete disassembly of the dash and removal of most of the interior. I believe it would be cheaper and less heartache to buy a car with nav already in it. Good Luck with whatever you decide. If you do this, be sure and post updates with pictures please.
