I have a 2010 Terrain with Nav system. When I turn my car off all of my XM channels are gone except for the preview and radio ID. When I resend the signal I get my channels and weather back but lose them after turning the car off again. I have called xm technical support and they say it is a GM issue, when I bring it to my dealer they say that it is on XM's end. Also I have had the nav system firmware updated twice for other various issues. Any suggestions.

That is a radio concern, take it to a competant dealer they can call GMTAC and get a new radio released and get it installed for you. AGAIN this is a radio concern not holding the activation and you NEED a new radio

This is very good advice to ask the dealer to involve TAC (technical assistance). I would also be willing to set up a case for you on my end as well. Please feel free to contact me privately with your contact information, VIN, current mileage, and dealer name for further assistance. Thank you in advance.
