Garmin Etrex Screen Kaput!

Not a total disaster but my Etrex went flying off it's mount the other day and now the screen is a goner. The device itself still works but as this is a cheaper Garmin model I don't know if it's worth getting the screen replaced.

I was a bit annoyed with myself as I had started using a tether but the time I didn't ... well there you go.

I have a bit of a problem as I'm doing a 100km Audax run a week on Saturday in the Malverns and whilst some kind of GPS is not required it is useful if you're in unfamiliar territory.

I don't really want to buy another unit so I am contemplating going 'old skool' and using the written instructions and a map!
