E39 M5 radio woes

[TheAngryDog]

More screen related issues today. Driving along and the radio went off and the screen became unresponsive and won't turn off at all.

If I stopped the car and turned it off I'd get radio for about a minute and then it would go off again. All while the screen did nothing. The coordinates were changing so it was doing something but the screen is dead except for always being turned on.

I have had the mk4 nav tested and it's been passed OK

I have a spare screen to try.

Could it be anything else? I have the hifi audio upgrade and intravee with kca420i.

Thanks

It's the screen. Just disconnected and reconnected it and it's working, though I think it's still faulty as it's flickering a little.
