  • Have an issue my headunit not powering up.

My first head unit powered up and it was working fine but the back up camera and steering wheel controls were not working. After I turned off my car, the unit couldn’t power up again. I bought another head unit, the same story.

Check the fuse on the back, it's blown or not. If it keeps blowing, then contact a mechanic to figure out why (or do it yourself if you can).
