Absolutely. This would be a sensible thing to do. So why aren't they doing this? My explanation (well, "guessplanation" would be a better term) is: all those (very) minor upgrades (e.g. 710 to 715) are nothing but cumulative MapShare corrections; those are free
Actually they are not. Actually it is impossible for new map (7.15) to have any MapShare corrections applied. Let me explain.
Even if TomTom escalated all MapShare changes made in 7.10 back to TeleAtlas and TeleAtlas corrected everything the latest map update we got (7.15) is to early to see those changes in real life. You must take into notice the timeframe between map release is done by TeleAtlas and map being pushed to users by TomTom.
I guess most folks dont understand how long it takes for a map release
to appear on our devices.
Consider the latest map. The 7.15 map published 5 Feb 2008 is actually based on TeleAtlas 2007.10 material, which means that the map is a snapshot of TeleAtlas data from September/October 2007. Now think
when MapShare really showed on market. The first devices showed up
around summertime, but considering initial problems, firmware updates
the realistic time before MapShare things was figured out is around October/November 2007 if not later.
So on 5th of Februrary 2008 we received the map that was published by TeleAtlas even before MapShare was really working on TomTom devices.
So considering just the dates it is almost impossible to have any MapShare updates being applied to the 7.15 map, unless TeleAtlas staff can travel in time
So considering the TT escalated all changes to TeleAtlas and they applied them I think the earliest release we - as TomTom users - might see those changes beeing applied to TA maps is their 2008.1 release (that will be published by TT in 3 months, or 2008.4 that should show up as TT map
in 6 months).
We got this map today, but this map is really 6 months old.
