Can anyone adise on the current GPS software out there - it looks like you have to pay a subsription for most but is there one that I can just buy out right?

Also, for those of you using GPS on your mobile - does it cost much to use it? how is it charged? do you pay your network or as you are using the software do you pay at all?

I have tom tom 5 mobile on my p910i and it works brilliant just the same as the tom tom 300. You dont pay any subscription , you only pay for extras like , real time traffic and speed camera alerts if you want them.
