Thanks for the reply guys.
Stevie, basically I just wanted it to do Sat Nav after seeing my mates, glutton for toys but have now changed my mind [see comment below]
Irving - nice install, I'll get some pics up of my setup when completed.
I made a decision to get an HP iPAQ 2210, Royaltek GPS mouse and car cradle last night, the reason why I got the iPAQ was because of the CF slot and I've already got two 256mb CF cards at home which I can use and would save me money having to buy SD cards.
I've also been using an iPAQ here at work and have been mightily impressed with it, I'm just testing it at the moment for a work application but keep taking it home each night and playing around with it
I'll keep you posted and will probably be back for questions on the setup soon
Thanks again guys.
