Need some expert information on my recent install. I upgraded my head unit to a D3 from a Pioneer DEH-P7700MP. I wanted to use the same XM components (Pioneer GEX-P900XM and the Terk XMDPI0100 digital interface) with the D3 that I had on the 7700 but after the install the D3 will not recoginze the XM stuff. I also have the bluetooth box (Pioneer CD-BTB200) hooked up and working. Anyone got an opinion?

The terk stuff works like crap with pioneer navigations. You have to buy the pioneer box instead
