I too have failed with the GM12-PCPIOX from PIE.I will be resorting to FM Modulation but am undecided between wireless and wired. Opinions???Is anyone going to try this? Will it work with non-XM Ready factory Vibe radios?http://www.xmradio.com/xm_dire...d.jspBoy is GM missing the boat on this one if...

Hello all...I have a 2004 Canadian Vibe.Does anyone with a factory installed XM Radio know the actual part number for their radio?Also, is it the single CD or 6 CD unit?My part number is 12231689 and it is the single CD unit with the 200 Watt amplified system.Thanks

Forgive my ignorance but what are T-Taps???Would I put these before the factory amplifier (ie] the inputs to the factory amplifier) or after the factory amplifier? (ie] the output of the factory amplifier)Thanks for the quick reply....

I have the diagram, now which wires would I hook up to my amp for either a sub or a set of 6x9's in the rear? Do I have to split some existing wires?I don't want to lose the existing speakers and amp setup. That is, I want to add another amp.Thanks
