The recently released (Q3 2012) Garmin Zumo 350LM appears to lack track import capability. Independent testing as well as discussions with Garmin Dealer Tech Support confirm this.
The Zumo 350 tested was updated with the only OS service pack update to date.
Testing shows:
1. Sample track created in either Basecamp 4.0.2 or Mapsource 6.16.3 and exported to the device is not resolved. No record of any track shows when the device is on. The file sent is queued as a "Temp" file in the /GPX folder but no further manipulation or import is done in the device.
2. Routes are correctly resolved and appear.
3. Waypoints are correctly resolved and appear.
4. TracBack feature works properly.
The entire Zumo model line as of date has allowed for advanced track importation and manipulation. However, the Zumo 350LM has departed from this advanced and necessary feature routinely used by off and on road motorcycle enthusiasts. Other disciplines use tracks on Zumo's as well.
Questions?
1. Was this a design feature that was purposly deleted? If so why?
2. Can a firmware or software upgrade be pushed to the device to reinstate this functionality to mirror other Zumo models if warranted?
3. Are there any current or immediate workarounds or alternates available?
