Just tried to install one of these modules into a 2006 escalade with factory nav. The i-pod would charge, but would not come up through the XM band on the radio. We ended up putting a different module in it

 

Do you think it didn't work because it is only listed to be compatible with 2007-2008 escalades?
Looks like it is for most 2007-08 vehicles...
Just curious

 

Im using the iSimple version of the pac piece. Escentually the same piece. Works well. what would you like to know?

 

Thats probably what the problem was timmy.....Our parts dept sent it out to me saying that it would work, and they even called PAC when the module didn't work, and they didn't say anything about it being too old of a vehicle.
