Smulan mate, that's also excellent targeted advice for biker use and very easy for a novice to learn with MapSource to do the waypoints. Thanks. You should start a thread with tips for workarounds such as using waypoints with split maps in units like 276C. There's a surprising amount of these old 'region only' waterproof units still in use. Many are restricted by small datacards or insufficient internal memory for detail maps. It's possible to buy a [Only registered and activated users can see links. ], [expensive!] but those with limited internal memory and no media card slot are forever stuck. All these workarounds are scattered around, having them in one place would be helpful for bikers i believe.
