I have used a 1030 and now a 1030 plus for navigating on multi-week bike tours. On my recent trip the 1030+ stopped showing chevrons while navigating a course. Without the chevrons I found it difficult to tell where the route was. It did show the arrow representing my current location. I did a factory reset and I started getting an error message "Cannot un-lock maps" I managed to get by, but now I am back I have re-loaded all the maps and did a factory reset on the device. It looks OK, but I am yet to use it in anger. Anyone else had a similar issue? I noticed this morning a new version of Garmin Express, which seems to have new map functionality. Cheers Jim
