It is pro'ly just a TomTom OV2 POI file that is sent by Google. TomTom at home may then load it on the device as a favorite, and there ya go.

Older TomTom OV2 files can be converted to Wayfinders NCE files and we have already figured out how to load them on Wayfinder. >>http://www.internettablettalk.com/fo...ad.php?t=11911
Newer TomTom OV2's are backward compatible with TomTom devices but involve a different encryption scheme. Prol'y as a result of this Google dealio.

When these new files are cracked, it will be easy to craft an automagic loader for Wayfinder... if they can be intercepted. (I don't know how Google intends to send them. As an email attachment?)

The same may be done with MaemoMapper but, I don't know how it handles POI's
