Clie NX70V with TomTom?

New member to the forum, so be gentle!

I've been using TomTom 2 with a cheap Pocket PC. Generally impressed with the software, but frequent lock-ups which I believe to be down to the lowly PDA discourage me.

I've also got a Sony Clie NX70V and I was wondering if it might work better on this? Has anyone had any experience of this set-up? If so, what do you think and what do I need to get this Sat-Naving me aound the country?

All comments on Clie experience welcome...

Cheers!
