Jay Bamrah 29 Report post Posted April 22, 2021 Hey, I replaced my car battery, now the sat nav screen doesn’t turn on so I can’t use radio Bluetooth apple car play etc. I have an aftermarket system which is a pioneer something, the old owner installed it. does anyone know how I can fix this? I doubt many have the exact same sat nav screen as me but maybe it’s a generic thing to fix? thanks:) Share this post Link to post Share on other sites
