What's the best way to use this device moutainbiking? Recording activities works well enough but what about using the maps and navigation? I've used this and a few previous Edge device on the road and except for the bugs and glitches, it's pretty straightforward. I was pleasantly surprised to find that a good number of the trails I ride show up on the OSM on the device. Unfortunately they're almost impossible to see due the fact they are thin black dotted lines on a dark green background.
I tried creating a course in GC and it won't follow trails as far as I know. But! I just tried RWGPS and I can create a course that follows OSM trails!!! I'll have to give that a try and see what navigation cues I get.
Of course if I'm just riding around it would be nice to be able to see OSM trails on the display. Is there any way to make them more visible? Perhaps if I know the area I'll be riding I can create a course that covers all the trails and then have it display on the map without navigating it. Is that feasible?
Update: I just laid out a GPX course in RWGPS on trials and had the 820 navigate it. It showed the course on the map. It alerted for some of the turns at intersections with bleeps and white arrow depicting the upcoming turn on the map. It did not show any textual turn instructions or count down the distance. It didn't alert for all turns at intersections, which may be a property of the map database. When it alerted with I intentionally deviated from the course twice and it alerted me each time. However, it did the same thing I found while riding on the road and that is the map stopped updating at the point of the alert and didn't continue to update my position so I didn't know where I was in relation to the course to get back on it. I don't know if swiping away from the map and then back to it would rectify this.
