NAV/TV No sound
 

I have no sound from my TV or NAV, the radio and CD work fine. When the TV option is selected it does not ''overide' the radio which stays on. My X5 has DSP which works fine. Any ideas?

Many thanks, Ian

Hmmmmm.
If you have MK IV nav, dissonect battery for a while 10 min or so, that will force all units to reboot. If you have MK III you can still do this but there is a procidure so your MK III dont die.

The procedure so that the MKIII doesn't die is to wait for the red LED on the MKIII (or any nav unit, to be safe) to go out before you pull the battery cable or disconnect the nav unit itself.
