thanks
any luck with...I'm looking to do the same
Most CD changers have the modulator actually within the changer hardware itself. The 'adapter' that goes into the dash is usually just a relay that switches between passing through the factory antenna input, and the input from the modulator inside the changer.
Most changers that i've worked with are like this, Clarion, Sony, JVC, Audiovox, and no-name brands. If this is the case, you're pretty out of luck trying to 'adapt' it.
If you have a newer XM unit, pretty much anything newer than a Roady or a SkiFi (like the Roady 2, or SkiFi2), they have FM modulators built in.
