Hello all -I just purchased an 07 Armada the other day, and so far love it. Only problem is it came with XM preinstalled, but I am currently a Sirius customer. Dealer was a little hesitant about swapping the XM receiver for a Sirius one. Now I've done many a car radio install in my day, and was wondering if anyone knew the level of difficulty of swapping XM for Sirius? Also, where could I get the Sirius receiver, since I assume it's not built in to the factory system, but a small box like the aftermarket ones.
Thanks in advance!
