uploading from Zumo to Mapsource
 

Data from recent 4,200 mile trip (waypoints, tracks) will not upload from the 450 to Mapsource.

Advice appreciated.

Thanks,

Did you leave the Zumo powered-off when you plugged it into the USB port and then wait for it to write all the data to a .GPX file?

Yep. The Zumo screen showed status bar indicating upload but data did not show up in Mapsource.

You will need to pull the archived track info manully. You should have been able to transfer (recieve from device) the first 10000 track points and all the favorites and routes. To get the rest of the track info, they are on the unit, what ever drive letter it got mapped to on your computer. Like E: They will be in the \garmin\gpx directory\archive directory. The file names will be a number .gpx. ie 3.gpx. The higher the number, the newer the file. You will need to open those with Mapsource and you will find all your track info older than the most recent 10k points. It keeps 19 of these files, so between the active log and these archives you have 200,000 trackpoints. Plenty to cover your trip.

Ta very much
 

Now THAT is good info! Just found some tracks that i thought were lost forever.
