Recommend me a GPS unit!

[Highlander]

This maybe or may not be of any use, but I got myself a new smart phone the other week, and one of the few apps I down loaded was a GPS app.

The scale of the map isnt really important because the system uses google earth, so you [ the little animated person] is standing, and moving over the photo

I have yet to test it properly though, so cant recommend it yet, I want to see if it will get me off the hill and to safety [ I will pretend it is foggy]

Its just that although I always thought I knew the hills around here like the back of my hand, I got lost this last winter in fog,..which was a bit worrying,... hence I will try this app

I am hoping that it will be a handy emergency application
