So I am not interested in changing to an aftermarket deck, I just want something that plugs into my radio, sounds good and has the interface controlled through my stock radio. I just need a harness of some sort and a tuner with an under the dash mounted antenna. Any suggestions?

 

i don't know if it would work, but you might want to look into getting a factory deck that had it and add the antenna and all that if you want to keep it all stock. just a suggestion

 

I took the XM tuner out of my 06 when I added an after market deck. If you have the harness in the dash you should be able to just add an antenna. Let me know if you're interested.

 

Easiest way is to look on ebay for xm radio upgrades for gm. They sell the adaptor and xm tuner module that will work through the oem radio as you are wanting to do. It works as the factory unit does.

 

This would be ideal, can you point me to a good reliable product?
