Currently use a very old Garmin 60 series GPS unit, mainly when i'm abroad for a back up against paper maps.
Quite fancy doing a load of UK based off road riding this year, and would really like some kind of bar mounted solution with an OS map loaded which i can pre plot a route on and just follow it.
Been quite inspired by the lakes 200 route someone posted on here and will probably do it over two days with a bivvy.
Should I buy a new GPS unit or will an iphone 4 suffice?
I really want to be able to upload gpx tracks and then follow them.
