2012 CRV. love this car, no real issues until last month. One night display screen worked fine, next morning BLANK. Also the radio controls on steering wheel will not work (chg stations, increase or decrease volume)...stopped at the same time as screen. Dealer didn't know why, computer check up revealed nothing. Can replace display for almost $600 (parts & labor). I thought it could be a fuse, but they said no. No driving issues w/o it, just miss convenience of back up camera, station & clock displayed. Any ideas ???
