    Hi,

    I'm trying to find the GPS wire that comes from the sharkfin antenna and goes to the OnStar module. I want to put a splitter on it and send that to an aftermarket stereo. The factory XM unit is getting the same treatment soon as I already know it's location and plug type.

    I have a 2008 Cobalt LT with OnStar and XM.

    Thanks!
