parking assistance bleeps

[richardcit5]

Hi can anyone help ?? Parking assistance still works (shows on multi-functional display) but NO sound signals. Also, radio/CD no longer opperates, and the 'MENU' button does not bring up any screens on the multi-functional display (so for example, I can't adjust time, use trip computer, see warning log, etc). Checked fuses F8 and F10 under dashboard, and they are OK. All this went wrong at the same time. Otherwise car seems fine. Has anybody any ideas how to solve this problem? Thanks!
