Hello I'm new to the forum and I am dealing with a frustrating issue. Recently I tried to install a new head unit and after wiring it up i realised it was not turning on. I pulled the connector off and realised I'm not getting ignition voltage to the radio. I have 12+ volts on the battery wire and a good ground at the head unit but zero ignition. I check both radio fuses under the driver side kick panel and they are fine. I also checked the room lamp fuse and it is fine as well. I pulled apart the tcu and there is no signs of a burnt board or broken line. I check the ignition switch to make sure it is sending the voltage when switched on and it is. Does anybody have any ideas on what could be causing it.
