They gave me the DVD and after checking with their service people arranged for me to have this "Ten minute upgrade" for £23.50.

However, after taking the car in to them and having this done I checked the settings page and found it still said 4-1/30 - in fact all they had done was take out my new 2007/2 map DVD and replaced it with another one that was the same.

They then said this was a misunderstanding and they could not do the the O/S upgrade to give me further functionality and did not charge me the £23.50.

I then emailed BMW UK to ask them why a dealer would say that I could not get increased functionality by upgading the Nav O/S. After a few emails I got the message back that they had tested it and informed the dealer that they could do the upgrade and I would get increased functionality including postcode input.

I have just phoned the dealer to get the upgrade done and they are now saying that BMW UK have told them that "although unusual they can do a whole car system upgrade for me". They want the car for a day and say they will be charging for an hour of effort at £141. My protesting that it only needs a CD putting in the car for a few minutes just to do the Navigation software cuts no dice with them.

My question is this: Should I take the offer of the whole system upgrade on a 3 1/2 year old car - or am I just wasting my money and I should just download the upgrade from your suggested sites and do the Nav upgrade myself?

I was willing to pay £23.50 to be perfectly legal and not seen to be cheating BMW - but they just seem to be messing me around.
