Hi,

I've activated a TomTom with a P900 Vodafone handset.

The TomTom website carries a compatibility index which you can check at
the following link:

http://www.tomtom.com/phones/?

This takes you through to a compatibility index. The compatible models
provided by TomTom may vary. For the P900 you would need TomTom GO 300
or the TomTom ONE

Hope this helps
