This drives me absolutely nuts to be honest.

When 2006-1 came out, my home address had been incorrectly referenced (wrong road name) and many roads around my locale were wrong. I contacted navteq using their responder and eventually had an email back saying that they had verified that the addresses WERE wrong and would apply an ammendment.

I buy 2007-1 and lo and behold they are STILL wrong.

It's shoddy considering I know that the TomTom mapping is correct; We pay a 'rolls royce' price for a 'lada' product as far as the BMW map disks are concerned.

I would like to be able to check the updates before I purchase - there ought to be an on-line facility to see revisions so you can see if you really want to fork out £200+ (legal dealer price!) for what is a very out of date item.

I suggest you try contacting NavTeq via their report form and see what you get back from them.

edit: has anyone looked at the mapping data to see if it is possible to enter our own changes? - that would be cool.
