Hi all. My hmi was damaged by water when it was at the body shop which caused the radio to stop working only black screen. I bought a replacement hmi off of ebay and now I have the radio with theft locked screen it works when the car is completely off sometimes but when ignition or engine is on it switches. I took it to the dealer but they said could either do it successfully or it won't work at all but they'll charge 130 regardless. What else can I do?
