traded my old outlook and td up for a td gt today. well after the install i noticed that my xm was not even showing that it exists on the radio. I also have a u1300 code. ive tried returning truck to stock with no luck. any ideas?

something i just noticed that is interesting is that after i shut the truck off is that the radio button lights flash on and off. this quits once i either flip the switch to "on" on the obdII plug, or unplug the gt completely.

oh and i yanked the radio thinking there was maybe a fuse. the thing was too hot to hold.
