I had read somewhere that I could use a GM factory antenna which provides outputs for GPS/Cellular/PCS on my 06 colorado.

I also read that it has 2 Coax outputs. My question is this, my navigation unit is a Kenwood DNX7100 and uses a funky little gray plug that just presses in, kind of resembles a round XM plug.

My internet car is an Air Card from AT and T, Is there any way to tie those in to that antenna, like are there adapter cables available?
