So I recently bought what was supposedly a done Mazda 3 however was just a battery issue so decided to keep it. She is in decent shape so replaced some stuff however the radio I put in a 2din touchscreen that sounds amazing.....except the moment you put the car into any gear it shuts off and will power on and off as you drive. I am at a loss thinking maybe not enough power to thge unit? Checked wires and found nothing as only happens when the car goes into gear. Any advice?
