Just done this!
anyone running version 2 tomtom home be wary, my 'update' would not load and this in turn crashed the version 2 making tomtom home not work.....
Long story short, everything has to be deleted and tomtom add a little extra in the system tray - ( I did a google search on how to remove from the system tray) - this still did not work, after a couple of system restores and registry clear up the problem fixes and the file can be removed.
So, if you do it be prepared for it to crash mid way, then find everything tomtom related on your computer and delete - anything that would not go I'd google (lots and lots of info found!) then upload from tomtom website version 1, once the tomtom is connected it informs you that there is an update.
This installed straight away removing version 1...
computers
Anyway, the update is excellent, mapshare, all sorts of extras, itinery recording (not played with it yet) downloadable 'pointer' logos - (there are 2 r1200gs's)
no 1150's so I've ended up with ecto 1 out of ghostbusters
Lots of sports bikes though
Emergency features with full first aid instructions for the untrained, lots more stuff to play with and some power save features not seen before.
Not sure if the add on off road trip computer thingy works on it yet.
All in all much better set up, mr tomtom must have heard me trying to convince the long haired general that I needed a Zumo for the upcoming road trip!!
Now the power connector fault has been fixed (bodged..) I think this has now become a much more reliable unit.
Certainly saves money for people thinking about an upgrade to v2 or zumo!
