I don't understand the electronic stuff so please bare with me.
Is the FM modulator something you hook-up to the back of the stock radio. Does it have to be powered by itself or does it get power from the XM unit?
When powering the XM unit, which wires do you splice into. In other words how do you power the XM unit?
Just thinking about this electronic **** give me a headache. Screw it, I will just keep using CDs.
