I’ve bought an android radio system which all works and displays fine. The issue is there’s no sound, if I disconnect the cam bus decoder and reconnect it the sound works for about 3 seconds but then goes off.

I finally gave up after a few hour and put the RNS 510 back in, this now has no sound either but displays like the android one. I’m stumped the RNS worked an hour ago now no sound even on max volume.

Any help would be great!

I have no idea why that's happening, but if I were you I would try disconnecting the battery for a while.
