On my 2011 Tucson - rear camera just went blank - not working - Brought it to the Dealer in Elgin IL. they want $515.00 plus tax to put a new one in..... has this happened to anyone else? Seems to me that this should not be breaking - My Toyota RAV 4 with 140 thousands miles on it has no issue with the rear camera / I tried to do the reset that is for the radio - no luck - I slammed the trunk about 5 times - still not working ---
