Can GPS fail? (and good, cheap GPS)

[ForgeCorvus]

Don't shoot the messenger, I was just correcting an error from a previous post (that GPS won't work without a phone signal).

I'm a great believer in using map and compass, I'm teaching my six year old grandson to use them, but I have a place in my pack for a hand held GPS and my smartphone too.

NavFree is a free app which lets you download a complete UK street map so no phone signal needed, just GPS

I'll mention that to Herself, save me from having to print out streetmaps when we go somewhere new
