The Edge 705 can 'navigate' or 'display' a GPX track. I have usually 
used the 'display' setting. I do not remember that 'navigate' would be 
broken. It just takes some time to calculate the route along the track.  
Could it be that some way segment is missing or unrouteable on the map?

The Edge 705 can also display a 'virtual partner' and a 'activity tcx' 
(or was it 'course tcx'?) on the map. That one would use turning prompts 
that are embedded in the file, as far as I understand. I have used this 
TCX feature only a couple of times. On longer bicycle trips, I had the 
Edge display a downloaded GPX route on the map and let it calculate a 
route (car, shortest distance), mainly out of curiosity. The bicycle 
routing only works well for a few kilometers of distance.

The Edge 705 is my only Garmin device. Its main use case was recording 
routes. Last November, the USB interface broke, and I could not figure 
out how to save routes directly to the SD card. I got a SonyEricsson 
Xperia Active as a replacement. The GPS sensor feels a little less 
accurate, and the offline routing on OsmAnd has a long way to go. Once 
the snow melts and I can do longer bicycle trips, I might still use the 
Edge for navigation.

Best regards,
