There are issues with this Firmware. This firmware should not have been released without proper testing. My advise is not bother to "upgrade":Hi, I have got the same here, but I think you should now upload to routes and choose PC routes. This is what I did and it is showing the map, it thus not do that in trackback activity. the good thing is that it is possible to manually zoom in or out. I did not ride with it yet, but is promising that the total course points where showing more than 4000 points. I have a Garmin 810 now and use the Globalsat Gb580p a lot less. This was mainly be course of the lack of manual zoom and to less smart track points.
I'm posting what I wrote on the other thread as this firmware now has its own thread:
"I had issues with the V2.0 201402241 firmware. I upload a KML file to the device and it upload fine but when I went to Activity > Activity Info > Training Info and selected the uploaded KML then tried to Track Back > Forward. It just showed "Start" for a while (15 minutes while optimizing the file I guess) and then went back to the activity details screen but none of the buttons responded. The only way to get out of there was to turn off the unit and turn it on again. In other words Forward navigation does not work. Did not try Backward navigation.
I downgraded back to firmware V2.0 1305232."
