I just finished my Kenwood 6980 installation on my truck. I have the Sirius Connect in the glove box, ipod interface, and have the factory aux hooked up.
I am also using an Axcess ASWC to use the factory controls.
Both Sirius and GPS antennas are in the dash, Might have to move the Sirius antenna later, but the GPS antenna gives 10 ft. accuracy.
The 6980 requires a very precise file format for uploading, so I've included the file I used here.
Thanks TW for all the threads on how to get everything apart!
