So both devices can display a .gpx file? That is great.
I would like my GPSMAP 60Cx to do that. But it does not. Well at least I do not know how it would. It can produce .gpx files. Actually it makes one .gpx file for every day it is used. It can hold the logged tracks for 100 years (on a big card). But it cannot show it’s own .gpx files. I consider this the biggest missing feature of this great device. Sooo often I came to the same place a year later and wanted to know how I drove in that town before. But not possible.
Vista HCx: I declare an external GPX-file (at my computer) as ACTIVE_LOG to prepare the track for uploading to the Vista HCx. Then I upload the GPX-file with gpsbabel to the Vista HCx, there it will be shown in the current log. Afterwards I save the track in the Vista HCx with a name as seperate track and delete this track as ACTIVE_LOG to make the log empty. This stored track can be used again and again (together 20 tracks in the internal storage, unlimited tracks at the SDHC called chip in the menu, each up to 10000 trackpoints) as track, for TracBack or only to show it at the map.
Oregon 300: Here you can use an uploaded (to the internal storage via USB or to the SDHC via USB or cardreader) GPX-file directly without changes, but not for TracBack.
At my Computer with Mapsource? But if you made an ACTIVE LOG out of a .gpx file then what is the result? Because if you upload the .gpx file with gpsbabel then what happened with the ACTIVE LOG? Please elaborate bacause I cannot follow your procedure.
GPX-files are the source (from friends, from gpsies.com or somewhere else)
I change the header and the title of the GPX-file to ACTIVE LOG (at my computer with a texteditor)
I store the current log in the Vista HCx to a track (to save it, if it is needed) and/or delete the current log in the Vista HCx (if it is not needed).
I upload the GPX-file with gpsbabel (I use only linux) to the Vista HCx
it will be stored as current log in the Vista HCx
I store this current log (= content of my GPX-file) as track with a name (bike-tour-danube e. g.) in the VistaHCx (not at the SDHC, because it cannot be used from SDHC)
I delete the current log
I can load one of the stored tracks (I wrote about GPX-files, this is false, you are right here!!!, but the track is the track out of the uploaded GPX-file) and use it to display on the map or for TracBack
I can store 20 tracks insite the unit and use these tracks (each up to 10000 trackpoints)
Because of the useage of GPX-files as source for my tracks I wrote in my former post:
TracBack is working with all gpx-Files, not only with an actual Track
It must be:
TracBack is working with every track uploaded from a GPX-file, not only with the actual track
And I used GPX-files in my description because it is a common file format. I can also use other files for this purpose.
Think that that is not happening. GpsBabel will convert the .gpx to an ACTIVE LOG format and then upload that to the device.
Yes. Not as a .gpx file.
This is a confusing formulation. The trackback capabilities of the device have nothing to to with the origin of the ACTIVE LOG. The device can not only track back the active log but also routes from intern memory or card.
Indeed. Thats why it is so confusing because .gpx is not a feature of the device. And you were comparing two devices.
GPX-files can be used with the Oregon 300 without converting these files!
Store a GPX-file at a SDHC or in the internal memory of the Oregon 300 and you can use it as a track shown at the map. You cannot use it for a TracBack.
You cannot use GPX-files from a SDHC with the Vista HCx and you cannot use again the stored track (which is also a GPX-file) if the storage place is the chip (SDHC) with the Vista HCx. This is only for external useage (tracking for OSM or other purpose). The tracks will be listed and you can delete these tracks, but you can only use the internal stored tracks within the Vista HCx for TracBack or showing on the map.
