Right, I can see all that on HBPC when I loaded the track to an sd card and then on to my unit. The problem is when I go from my unit back to the pc is where it gets lost.
Also how to it turn a .ht file into a gpx on hbpc? Been searching but I can't find the info anywhere.
HBPC storage-structure is in GPX files. A HBPC GPX basic file contains:
The default Waypoints folder
The default Routes folder
The default Tracks folder
The Groups folder with the HOME group.
The SD-card will contain a folder called MATRIX:
MATRIX folder "will" contain a file DATA.HWR which holds all waypoints & routes.
MATRIX folder "might" contain files called nnn.HT which each holds one track.
IE. If you have 3 tracks, MATRIX will contain 000.ht, 001.ht & 002.ht
When you Select All and Export, then your unit will EXPORT its data creating(or overwriting) the MATRIX folder and all files contained.
HBPC can download the entire MATRIX will all waypoint, routes & tracks and it will create a new GPX file called SD_yymmddx. GPX.
HBPC can upload one of its GPX files onto the SD-card back into the MATRIX folder. You will be prompted to ADD or REPLACE. Choose REPLACE to completely delete and overwrite the MATRIX. ADD is a more complex discussion.
That sort of explains Unit-to-HBPC and HBPC-to-unit.
Now if someone has created & send you just a .HT file, then HBPC can handle that also.
On the HBPC menu-bar select File-->Open or on the HBPC tool-bar click the File-Open icon. The dialog-box will open:
Under Files of Type you have option to open these file-types:
GPX File(*.gpx)
Humminbird File(*.hwr, *.ht)
Garmin File(*.gdb, *.mps)
Lowrance File(*.low, *.usr)
So far a individual HWR or HT file you would choose file of type Humminbird, then navigate to location of your HWR or HT file on your PC or on the SD-card. HBPC will open this HWR or HT file and convert it to its GPX file which you will see in HBPC.
That's the basics.
Salado has show this in his example, but he has also created and is using GROUP's.
