2006 freightliner classic factory sirius

i was nosing around in my under bunk door on drivers side today and found out my truck has a factory installed siruis antenna and reciever moun ted to the under side of bed. i originally thought it was just part of the qualcomm from prevoius owner. i do not have the factory radio that came in the truck so can i get a new single din radio that is sat ready to work with this reciever. i would like to find a kenwood but any would do. do they make a adapter that would let me connect this with a aftermarket radio?

 

[h=1]this is the unit that i have. google doesnt have much on it. seems like a common part though

SERIUS DELPHI DELCO SATELLITE RADIO RECEIVER/ ANTENNA MODULE/Part 12212840 / GM[/h]

 

i will have to pull the dash and see if i can find the sat plug wires. the radio that is in there now is a panasonic but its not sat capable so maybe he left the wireing for the satalitle alone
