I didnt. Tech did it. Fuse was blown, dude replaced it, plugged radio back in and blew the fuse again. Said he could smell burning in the unit. Based on that they say I need a new M-ASK, screen and iDrive controller are apparently still good.

Think I might get a used one off Ebay, seen one for about $300, would an independent shop be able to do the VIN coding?
