Well from the amount of post I have read so far, I believe that I should be fine, it's a Sony Muti-Media radio 55x4 channel and ordered theMetra - Speaker Connector for Select Volkswagen Vehicles - Black Model: VW-9000 along with the antenna adaptor .
The XM Sat module connects to the back of the radio and will tucked away behind the radio and the antenna will be routed to the back and placed on the truck lid since I read it has a very long cable.

If I run into any issues I will be on here asking for help. :-)
