Thank you! I had forgotten about doing that, as I only did it once on my Shaker about seven years ago.When I lost signal and sat radio wouldn't work I'd go to this site and send a refresh signal.
No need to speak with anyone.
The car should be out in the open and not in a garage that might obstruct the signal.
The only way I've ever seen an antenna fail is by physical damage.Yeah, you should check your antenna and see dealer for service.
My thought right now is a corroded antenna connector on the head unit.unfortunately, it might just do the actual head unit. a neighbor down the street drive charger scat packs. he has had 3 headunits go bad in the same car. 1st was delamination of the screen, then the next 2 just crapped out on him. it got to the point that he was going to hit them with a suit claiming the car was a lemon. the dealership and dodge gave him a new car. never found of what was causing this since he could never find anything about a tsb or recall on the headunits.
