Has anyone had problems with the motorized face sticking? It takes multiple times before it stays open or closed upon turning on the HU. Sometimes the headunit turns off by itself also. I have checked all power connections. I have been told that this first generation motorized units have been known to display the problems I have. Where is a good place with a quick turn-around to have the HU repaired. I remembered seeing a shop on Ebay offering repair for $60 but can't remember the shop name. Thanks
