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.<HR></BLOCKQUOTE>

The FM modulator gets plugged in series with your factory antenna cable. They actually plug into each other and then plug into your radio. As far as wiring the unit it is a simple 3 wire hook up. Constant B+, Key on B+ and ground. Very easy to install put one in my Supercrew last year. Great sound and quality.
