Ok, I am not sure about the plausability of this question. I have been told by installers that it is not possible to do without having schematics of the electrical system; which I am not sure they would have been able to read anyways.
A while back I installed an XM radio for my 2000 LS. The problem I have is that the integration to the head unit is not all the best. The antenna signal is fine using the FM Modulator, however the installer said it is not possible to make it so that the XM radio unit is powered on when the car is started. Every time I want to use the XM radio, I have to manually turn on the radio and when I turn off the car, the XM radio turns off, but the stereo stays on and goes to static until the door is opened.
I am under the impression that there is a power lead going to the head unit that is on until the door is opened. I would also assume that the power lead going back to the factory AMP, would be on this same power lead or atleast the same relay.
Is it possible to tap in to this power source to power the XM radio off of this lead?
Has anyone done anything similar?
