I can go into my device and upload the full Lap information. However it tells me that there isn't any Map and Graph information which I can't believe because everything you need to graph is there. And the map is on the devlce. I have downloaded the updates and still having no luck with it..
Apperently my unit had some old data prior to my purchase, (amzon selling returned equipment I imagine)
Anyway, I did a hard reset, (turn the power on while holding the mode button down) Erases all history. I then paired up my accessories again, tested it in 1 second mode and smart recording mode. The hard reset seemed to work for me. My 305 edge is now downloading map and graph data to my PC. Hope this helps anyone with the same problem.

I am having the same problem, my edge 305 says there is no graph for the item no matter which day or lap information I try to view. All of the other data is there but the mapping and graph data is not found.
