Hi, I just fitted a 5 channel amp in my 172 a couple weeks ago and things are starting to go wrong... first the remote for the head unit died, I measured it from the back of the unit and there was no current comming from the unit, so I hooked it up to another wire and now it works, but the HU turns off after about 20 mins of driving, checked in the manual its a "Logic on/off" feature so you can turn the power on without the keys.. anyway, for some reason the HU loss its "Logic" and thinks the car isnt running. Today the Clock display and Temp indicator decides to disapear and only comes on when I trun on the ICE... when I switch it off, the clock and temp also truns off. Whats Happening???? Should I just get a new Head instead?
