I guess my dealer is a little different. They made sure the viper / crossfire tech met up with me after the sale. To go over the specifics of the car. He gave me his cell number in case I had any problems. Told me to call if I had any issues. He also gave me the cell number to his service advisor, so I could schedule up appointments ahead of time. That way down time would be minimal.
I had the radio swapped out in 10 minutes. That fixed the roaming station issue, along with the dark display.
Each place is different, your best bet is to talk to the service manager. Tell him you are unhappy with the service you have been given, and you would like that to change. Throw out some suggestions on what would make you happy. Most of the time these guys are dealing with cheap'o customers. The service manager will give you one of his top guys to talk to each time you go in. I'm sure it will turn around in no time. Just give them a chance.
They are wrong about the service manual. Tell the service manager to check with the sales team. Also get the crossfire tech involved. The only person working on the car should be certified to work on the crossfire. I wouldn't let anyone else touch it. Verify they do in fact have a certified crossfire tech on hand.
Good luck man. Keep us updated.
BTW. PM me priv. Tell me what dealer / location. I might be able to help
