Hey all,

Tried to install an aftermarket double din touchscreen into my bora 4mot. Had in all swapped over and tested it without fitting it into the dash and it was working great. Then i turned it all off disconnected the battery and fitted it into the dash. Once id done so the headunit no longer turned on. I checked all the connections and the fuses and they were all fine yet it still wasnt working so i reconnected the standard headunit it and works. Then thinking the aftermarket headunit must have broken i tried fitting a different aftermarket one which didnt work either. So now im stumped as to what it could be.

Does anyone have idea on what it could be?
