hey all, i picked up one of these cheap locally as it has a problem

its the old "screen image may appear reversed" issue. after a reset or off power for over 5 mins when you switch it on it goes through the language then the press ok bit, the icons pop up for 1 second then its stuck in the "screen image may appear reversed" bit and i can get it out. i dont have the control harness but i manually simulated the handbrake and reverse pins and its still locked out and wont respond. am i being silly and missing something simple. 

when simulating the handbrake and reverse i assume you just earth them??

any ideas?

forgot to add this is a euro unit, ive been playing all morning and its just stuck on the camera, i cant get out of it no matter what i try and ive searched on here and tried about everything people have suggested

sorted

it was a 12v supply to the reverse switch not an earth. all came back and camera switched off

i think that it's a software problem!

i have The rear camera with 12v option select, if I touch The rear camera on The right top screen, The radio start one loop show black screen whit the rear camera message and after return to normally function and nex black screen.... The only reset metod is to disable the rear camera in the settings menu, exit and reselect the 12 volt option.
