if you have XM then i see no reason why you can't do this mod:My Manual shows that i do indeed have XM radio as well as XM antenna on the rear window. How do i check for the XM hardware?
The only thing you can control is the volume on the car NOT THE IPOD!Thanks for your help bullet, with your fm transmitter, can you control your ipod through your searing wheel controls.
Got tips on how to install or a DIY guide?Look at your options here: .
I have an 03 cts and I went with the fm transmitter (not the portable one!)
Your going to need
FM100A FM Modulator with IST2 Isolation Transformer
PH62089 Stereo Mini-Male to 2 RCA-Male
Radio Antenna Adapter Cadillac CTS 03 04 05
It works great. You dont get any static and it even works under tunnels or other areas where you typically wouldn't get reception.
BUT ITS NOT CD Quality but its better then nothing!
Hope this helps
I should have made a write up when I done it.Got tips on how to install or a DIY guide?
Thanks for the info. PICs would be great. waiting for my kappa 10" SUB, 1000Watt Amp, HIDs and LEDs to come in. I want to do everything while I have the bumper and rear deck/seat out.I should have made a write up when I done it.
The FM transmitter has a wiring diagram. Its very simple. All you do is cut and split the power wire (Its red and I believe its on the bottom plug) on the radio and solder it to the power wire in the transmitter (also red). Ground out the FM transmitter. I placed it between a screw and a washer its located directly behind the radio to the frame of the car.
Then Attach the antenna adapter to the radio antenna. I drilled a hold next to the cigarette lighter for the on and off switch so its hidden. Connect the PH62089 Stereo Mini-Male to 2 RCA-Male to the back of the FM transmitter, and either you can snake it through your center console or snake it to your glove box.
The thing your modifying is the power wire. Other then that the rest is plug and play
IF you want I can post some pictures
Hope this helps
