I bought my truck with the D2/xm receiver installed. Today I swapped out the xm receiver with the GEX-P10XMT so that I could utilize navtraffic. Now the gps is off by about a mile and a half and the clock doesn't work. anyone have any idea whats going on?

have you tried to reset it?

If the clock doesn't work, that means its not getting satellite reception. Did you plug the GPS antenna back in?

the gps antenna gets plugged into the back of the xm receiver correct?

No The GPS antenna gets plugged into the D2, and the XM antenna gets plugged into the XM unit.

ok thanks, that must be my problem then, ihave the gps antenna plugged directly into the reciever, but I'm still getting xm music fine?

I believe they are pretty much the same antenna. It's just that you need one for the XM and one for the nav.

yeah fix the antenna and your problem is fixed....

ok so i got the antennas all plugged in where they belong but now the time is incorrect by about 25 min. and the map wont move while i drive. but it says that im getting a gps signal, and when i go to vehicle dynamics it says they are unavailable but they worked fine before. whats up now?

Did you try resetting it?
