Hi,

I have just got a 330 CD M Sport Coupe, equipped with the professional navigation system. My phone connects automatically when the ignition is on, no problem whatsoever. But from yesterday, the telephone option has gone from the screen. I now have only 3 options, GPS, TV & Info - Whats happened to telephone and how do i get it back??

disconnect the battery for 3 minutes or carry out a battery reset.
hopefully it will wake up.
I have had a few recently that gone down and the only way forward is a new control unit.

Ps battery reset is take thew negative terminal cable off of the battery and short it to the possitve cable or disconnect both cables from the battery and short them together(dont have a battery charger fitted on).this will remove any voltage spikes
