Nav map updates
The cost to update the navigation maps in a BMW is quite expensive, especially considering that you can buy a lifetime update for something like a Garmin for less than $100 and it is included with many of them from the factory. But, we don't own a Garmin!
Has anyone found a reliable source for updated maps? If so, how did it work out for you?
Has anyone had their's updated at the dealer? If so, what did they charge you?
