I'm after something that will tell me about speed cameras but I don't really need satnav as I already have it built into the car - of course, having it for 'free' would be great - I only need UK maps. I was toying with the idea of buying a PDA again and was wondering what options there are for this. Ideally, i'd like to have a built-in antenna or a wireless (eg. Bluetooth) remote one.
The PDA itself should be a fairly decent PDA as well.
