nova headunit

[grgilson92]

right, need a headunit in me nova. tried 2. although one doesnt work and the other may not due to being in my old car that i totalled. have voltage tested the loom in the nova and its showing a reading. i then connected the loom i have for my aftermarket headunit and that was reading a voltage too. so my question is basically is there anything iv missed before i go out and splash out on a new head unit??
cheers

have you checked your wires are all in the right place for that particular unit?
