Hope I can provide some information here; The Geodetic Datum used in TomTom devices is WGS84.

Thanks. That seems to be the international standard for now. I just wondered if it was the same as my Nuvi because when I hold the two next to each other I get a fairly different reading. I thought maybe the TomTom was using NAV.
Thanks for the reply.
