I'm trying to analyse exactly what is happening.

As I understand it, Registry-based maps show correctly in Basecamp but lose detail when installed on the device.

Garmin provide a converter to make GMAP from Registry-based files - and JaVaWa offer one too (which works for me).

If Basecamp installs GMAP files correctly then the conversion is a simple way to get round this issue. Or am I missing something?

MAPC2MAPC will cut the large TIF images from CNIG (c14000x9000 pixels) into tiles for Orux (and others).
If you use MBTILES format then you can join several maps together seamlessly.

The Spanish Geographic Institute offers free downloads at 1:50,000 or 1:25,000 : http://www.ign.es/web/ign/portal/cbg-area-cartografia

MAPC2MAPC (also not free) will convert to KMZ and allows you to select tiles for just the areas you want - the map created does not need to be a whole rectangle.

If you already have GPX  files of your planned routes then it will create a Route map optimised to cover just the GPXs

And it will make JNXs too.

There is a calibrated version attached.

I changed the file name as some units can be fussy about long names and hyphens.

The coordinates printed at the side were a great help!

I used my MAPC2MAPC program to input the coordinates and output the KMZ.

This is full size and uses four 'tiles' of the hundred allowed in your unit.

I'm not aware of a third party tool - but I don't know everything.

pMail me and I will try to walk you through it.

But it can be done using push-pins to supply the coordinates.

Example here : www.the-thorns.org.uk/Landscape.kmz

If only the PDFs were GeoReferenced, then it would be easy.

The workflow would be:

1. Download a PDF
2. Identify coordinate points for georeferencing (see below)
3. Georeference the PDF by matching points to coordinates
4. Crop the collar to just leave the map detail
5. Cut the map into 1Mpixel pieces to make a KMZ for Google Earth and/or a Garmin Custom Map.

If you can match enough highway bends/junctions, lakes or other landmarks then this technique with MAPC2MAPC may work :

MAPC2MAPC (with GDAL) will do the rest.

But I declare an interest as the author of MAPC2MAPC!

I use an iPad with a GNS2000 Bluetooth GPS and it works well.

Take care when choosing an Android tablet. Every Android phone has GPS inbuilt but not every tablet.

You could get hold of a Mapsforge map (e.g Open Andro Maps), use Mobile Atlas Creator to render sections as a PNG then use an image editor to make a BMP.

But, to me, that doesn't seem the right thing to do for a navigation system, not least because the file will be vast.

You can get USTOPO in Mobile Atlas Creator with this code :

<?xml version="1.0" encoding="UTF-8"?>
<customMapSource>
   <name>USGSTopo Basemap</name>
   <minZoom>0</minZoom>
   <maxZoom>16</maxZoom>
   <tileType>png</tileType>
   <url>https://basemap.nationalmap.gov/arcgis/rest/services/USGSTopo/MapServer/tile/{$z}/{$y}/{$x}</url>
   <tileUpdate>None</tileUpdate>
   <backgroundColor>#000000</backgroundColor>

The tiles are already Spherical Mercator and MOBAC will write a Garmin Custom Map directly.

But it seems your maps are out of date - the railroad is no more!  ;)

MAPC2MAPC will reproject from most existing projections, doing the calculations automatically.

I suspect Garmin get roads etc from USGS. I have been working with USGS data and there are several errors - the worst was a road running through the middle of a lake!

CGPSMapper creates IMG and IMG.IDX files when it compiles a MP. Using Mapset Tool KIt, you need to copy the IMG.IDX files into the Mapset directory before you start the process of building the map.

C:\ProgramData\Garmin\Maps\ sometimes works for me!
