The update is only available via the TomTom HOME application, and apart from fixing various bugs versions 6.12 and 6.14 introduced, 6.15 also adds:
- Support for SD cards larger than 1GB
- Installed version 3 maps on the GO Classic are now recognised again by TomTom HOME
- Remote control of the GO 500 and GO 700 now functions correctly.
So basically, there is no new functionality provided by this release, but it does fix a host of bugs. Overall users are reporting a relatively smooth upgrade process. This update has been available for over a week, and so far there have been no major smoking guns, so it’s probably pretty safe to upgrade (although given TT's track record, it's anyone's guess...).


I would like you to email me the 6.15 home version to update my tom tom. Thank you
