What would be nice would be a lookup facility on Navteq's website to see what (if any) updates/revisions/fixes were applied to that version.

As an example, my house has been built now for 7 years. I reported an issue with the 2003 DVD where my house number (or that of several of my neighbours) didn't register - as of 2007-2 they still haven't fixed it (or 3 other issues I reported).

It bothers me that they release 2 updates per year at £200+ and we have absolutely no idea whether it would be of benefit - no wonder people clone the DVD's. I only bought one from the stealer last time as it was a £99 upgrade....
