Hi Guys,

I need help please with investigating the problem that I have with my NBT Nav.

The head unit is making a clicking / griding noise when it is stating up. Initially, I thought it was the dvd disc as the eject button wasn't actually ejecting the disc, so I've removed it manually, but the noise is still there.

Then I noticed that sign recognition only shows speed limits for a few seconds after driving past a sign, then the speed limit info disappears.

Navigation is stuck, it won't start.

I can make phone calls but I'm unable to stream music via Bluetooth.

USB drive with music is not getting picked up by the system.

I've uploaded a video to demonstrate the issue:

2015 BMW F32

Any advice please :( ?
