Got myself a TomTom One v2 (although it says v3 on the device software but it has a mem card slot).

I've tried to put Navcore on a 2 x gig card but can I get it working, can I fook!

Anyone got a simple step by step guide for a complete tomtom novice?

I'm using TomTom Home ver 2.5 and the device is all up-to-date and running version 7.903.

I'd even be happy to just be able to add speed cameras...if that's easier...

TIA.
