An old geocacher with a new gps is going mad... having spent 15 hours or so this weekend trying to get a small OSM map onto his gps. I've downloaded the latest Java, and also mkgmap-r2664 and splitter-r307 both of which I've unzipped. I've learnt lots about navigating in command prompts but keep hitting snags, taking me back to the days of DOS some 30 years ago! Could someone please just give me an idiots guide? I'm using Windows7 and have a Garmin eTrex20. Any help would be very much appreciated. Thank you.
