TomTom has announced new features to their TomTom PLUS service. New services are TomTom Buddies and TomTom audiobooks. The TomTom audiobooks is self-explanatory and should provide audiobook downloads for the TomTom GO 910.
The TomTom Buddies service is a little more unknown, however we should have new information any minute now. We suspect this service might be similar to the TomTom WORK system, however for families instead of corporations allowing a GPS location to be broadcast over GPRS connection to locate where your friends and families (thus TomTom Buddies) are.
