Ok, this might sound dumb but I just installed my Apex-i TT with the harness into my car. The problem is that the thing won't turn on, I am pretty sure i installed it correctly (opening the steering wheel part, disconnecting the old wires and reconnecting the new ones). Could the TT be defective or is there way to get it to turn on? any comments or help would be much appreciated! Thanks.
