Is this correct? If so, do you get any kind of message to say you are being diverted round a problem?

Correct. When a delay is detected you will hear the message " xxxx , the route is being recalculated" where xxx is the reason for the delay. Sometimes this can get very annoying if there are several hold-ups on two routes that have a similar journey time - but you can turn it off in the usual way. Occasionally you also get a message which is something like "There are hold-ups on the best route, expect delays" that's not the exact wording, but it happens if there is no route without a delay on.

To play MP3's you will need a new (Sept 2005 or later) BMW CD Changer, the built in CD slot will not play MP3's on a Nav head unit. If you have one of these then you will get a new option under 'info', "AudioText". If you check this then you will get ID3 tags displayed on the Nav screen.
You need to get a cable to activate AUX-In, its quite easy to install yourself but it's not just a simple cable. There is a schematic for it somewhere (can't remember where) but basically it has a 300 K Ohm resistor between right and left channels. The radio uses the resistance value to determine if it should give the Aux option when cycling through the various sources.
