The only other strange thing I found was a diagnostic screen for engineers, which the only useful thing I found I could do was increase the Mic levels for the bluetooth?With the ignition on, but engine not started and lights switch in off position. Hold down the Info button, while holding down, switch the lights on, then off then on again, hey presto a diagnostic screen will appear. Play with the menu to test things? The Mic level settings are in the Bluetooth sub menu!
Not sure if it's any use, but worth a play.
The only thing that interest me is trying to find the override for the Sat Nav as it drives me crazy not being able to set while driving. I will keep searching. :tsktsk:
