I get lost all the time and have an actuall fear of trying anything too outrageous because of it ;)

I WILL be getting sat nav and I'm looking at this when it comes out in October

http://www.gsdnav.co.uk/NEW-ZUMO-i49.html

I won't use it for routes I know or have learnt using it but for a new route It will be invaluable to someone as err.....directionally challenged...as my self.

that looks good, something to keep an eye on :)
