Bad Luck! Glad you like the car. Some things take while to get used to. Yes the COMAND map database is pretty good, but the guidance algorithm has its moments - particularly with pronunciation of foreign places. It seems to me that you could have a case to threaten the dealer with a report to the Trading Standards Office or even the Small Claims Court. It depends on how strong you feel; it's a tough road to embark on.
Yes the "bear left" for turning right at large roundabouts is a bit hopeless! Maps themselves seem OK. Dynamic routing a bit questionable.
Pronunciation is a scream! I am thinking of putting it into French and German (which I have a reasonable grasp) to travel to Switzerland and see if "she" copes better.
