I've had an active subscription since I got my car. There have always been a couple dead spots in Vegas that consistently cut out. Now my radio is "linking" all the time. I've done a refresh several times and Sirius advised me to take it to the Stealership so they can check it out. When I called just to inquire how much this diagnostic was they said $165 and also it's problem not the radio if all the other functions are working. Sirius says this is not true and something else could be loose. Anyone have any advice on what could be loose or where else I could get something like this checked out? I'm about to cancel because at this point I'm paying for a service I'm not receiving in a vehicle that's driven about three times a week.
