Seen the write up in MBR. It’s only a brief paragraph but from what I can see and a utube video it’s a GPS guide you can upload route maps that it will indicate which way to go on a route you don’t know. Also Strava compatible and it’s only £104.
Anyone any experience of them, it’s my birthday in October and I fancy a computer to upload new routes to to help me find where to go without faffing with a map.
