Afternoon guys :) What could be causing this in the boot? The nav unit has been removed, all is in there is the DSP amp, BM54 AKA radio and TV tuner. Even with this unplugged I have the same problem. On the right hand side is the power distribution module / fuse box. There's no water ingress...

HIya, It's a brand new battery. It was put on literally 3 weeks ago. 100% the right one for the car. Also cant set the time on the radio or the date. No sound from the radio either. Actual gremlin I think! HELP!

Thank you Brian, will give this a go H x

Hiya, Did you manage to get to the bottom of this? We are having the exact same issues. Thanks
