OK, I'll try to make this long story short, but I have an XM Delphi SkyFi that is wired into my stereo (Blaupunkt - got rid of the stock CD changer) and plugged into my cigarette lighter.
Problem is, I get a tremendous amount of interference. I basically hear acceleration through the stereo, almost like having a second really whiny turbo. which would be sweet and whatnot, but it's not a turbo. It's supposed to be the radio.
Anyway, I called Crutchfield about the problem and they told me that the best way to go about it is to rewire the grounding in the cigarette lighter, because it's picking up too much interference from the rest of the car.
I trust him, cause he's not trying to make any money.
A bunch of questions. First is this good advice? If so, how to I access the wiring behind the cig. lighter. I've taken apart the dashboard before for the stereo installation, but not this. And lastly, has anyone ever done this before or had similar struggles making XM work correctly in their car?
