Thanks for reply so far everyone,still a bit confused over maps for the gps. Leaning towards Garmin as I know they are compatable with Google earth (no having to edit co-ordinates in like some brands,just copy straight in,) read that cheap models only come with cheap road type map. Think this means I would then have to buy expensive,more detailed map pack? Or do I need a map pack at all if just using it for taking me to location entered from Google earth?
My phone signal is crap,struggle with that whilst others don't so that's why I'm leaning towards dedicated unit.
Thanks for input so far,hopefully can come up with the definitive,reasonably priced,easy to use,urb solution!
