I have just uploaded a detailed map of France to GPSFileDepot. This is in GMAP format.

It is quite large - 6.5GB unzipped but includes every building, street names, woods, streams etc. It is mostly from IGN OpenData plus some itmes from OSM.

Corsica is in the map but not the French territories like Reunion.

The Inreach manual suggests the standard Garmin Topo maps are not compatible with the Inreach Explorer.

Is that true - and is there a way to make maps for it?

When compiling maps with cGPSMapper, there is an option POIIndex=Y/N.

But the Garmin IMG format contains 'Points of Interest' and 'Indexed Points of Interest' as separate data items.

It would be nice to switch indexing off or on for individual items (e.g index Hospitals but not trees) - is that possible?

I compile a Garmin map and install it in Basecamp. I then use Basecamp to install onto the MicroSD card of a Garmin Oregon where it appears as Garmin/gmapsupp.img.

If I now copy that MicroSD card is there any reason why the copies should not work in other Garmin devices (assuming, of course, the card size is supported by the firmware)?

I struggled for several days to get Road and City indexing working - but found a solution which I am sharing.....

I compiled everything with CGPSMapper (paid version, of course), copied the .idx files to the MapsetToolkit mapset files and ran MapsetToolkit.

But my normal NSI installer would not install the map with working indexes (I had  uncommented the relevant lines!).

Then I tried Javawa Map Converter to make a .GMAP folder from the Mapset, copied the .gmap to Program Data/Garmin/Maps and indexing worked perfectly.

I am building a Garmin map, one of the items being maps is a railroad. I am using the standard type X14 and have made a custom TYP file :

[_line]
Type=0x14
UseOrientation=Y
Xpm="32 5 4 1"
"= c #202020"
"  c none"
"3 c #202020"
"4 c none"
"================================"
"     =======         =======    "
"     =======         =======    "
"     =======         =======    "
"================================"
;12345678901234567890123456789012
string1=0x04,Railroad
[end]

Display in Basecamp is perfect - but on a Garmin Oregon some sections of track are displayed with spaced pixels - see attachments. Also, the railroad only appears on the Oregon when zoomed in much further than specified.

Any help much appreciated!

I am attempting to compile a map for several sources. Everything is working well except for named summits. I am using this MP code :

[POI]
Type=0x6616
Label=Pen y Fan~[0x1f]886
EndLevel=1
Data0=(51.88383,-3.43712)
[END]

The summit appears correctly in Basecamp but on an Etrex only the summit icon appears and the text + height only display in the title area when the pointer is over them.

Any assistance welcomed!
