I expressed my displeasure with XM a couple of weeks ago of not getting reception here in Alaska. They ended up giving me a credit for the 3 months I'm in Alaska.
The other issue I have been having is poor service from Onstar. Most of the time I've had good service in the parts of Alaska that I have visited, but here in Fairbanks I've had to have them download directions two or three times before it will be received by my vehicle.
And the third electronic item problem, is lack of service from Dish due to the In-motion dish that I have.
