So I jumped from the 500 to the 820 and was thrilled to find the unit's navigation was automatically telling me to turn right, left, etc. No more entering instructions manually!
Soon I got dismayed... while the unit made a song and dance at every corner in the road, at some T-junctions and cross-roads it was struck dumb...
Back to entering the instructions...
Then on longer rides the unit started to crash, seemingly on a turn where there was an overlap of instructions. (Generally I'm convinced the unit keeps on recording, it is just the display which freezes.)
Anyway, for LEL, I've decided to not enter any turns manually and follow the route sheet closely. That is not ideal, particularly at night. (No dynamo, so won't have the screen on all the time.)
Thought to look at the list of instructions the navigation generates (to fill in the missing ones), but this isn't shown until the start of the route.
Thought to use Garmen Connect, but get errors loading .gpx and .trx files.
Am I using the 'wrong' map? Should I turn off the navigation?
