TV Menu won't stay still

[X5_SSP]

I've just acquired my first X5. 2005 E53 3.0D M Sport.

Love it!

I've looked through this forum which has helped me sort out a few things like re-programming the keys, connecting my phone via Bluetooth, and I even think I've fixed the panoroof! Number plate light next - it was obviously working fine for the MOT a few days ago.

One thing I can't find any help with is the TV.

When I select 'Television' from the on screen menu, the TV menu scrolls across the screen right to left and is almost impossible to read. Following the list of menus in the handbook I've tried to re-scan the channels, at which point a message appears on the screen saying something along the lines of 'wait' or 'searching'. It eventually goes back to the previous menu which scrolls across across the screen.

I'm pretty sure the problem is not with the head unit as the dealer changed it due to a pixel problem.

All the other menu options work fine.

Has anyone seen this problem before?

I'm assuming as it's a 2005 model the tuner will be digital as well as analogue but don't know how to check.

Many thanks for any help.
