I bought a pioneer avh-1300nex and install it to my 2010 Toyota Corolla. When I went to try it out it would not power on. I put the factory radio back in and still wouldn’t turn on. The factory radio was working perfectly fine before in the install. I checked the fuses and wiring and everything looks good. I tested the power and ground with a dmm and it testing at 12.6 V. Everything else in the car works but the radio any idea why ?
