I bought a GARMIN ECHOMAP 92sv and I would like to know if I could make my cards like with my old lowrance?

I do see within Reefmaster that I can export to GPX format and can choose between Humminbird and Garmin. I just want to make sure that there will be no compatability issues with these newer Garmin units and Reefmaster exported data?

Unfortunately it is not possible to make maps for Garmin units in the same way as we can for Lowrance and Simrad units. The best you can do is export tracks in GPX format, which Garmin can read as trails. This won't give you a map, buy you can use trails to show an outline of an area, for example.

Try this converter:
www.rusfishing.ru/forum/threads/360704/page-1000

It is quite simple. Select the KMZ (vector map saved in RM) file and click the Start button.
The resulting file GMAPSUPP.IMG put in the \Garmin folder on the device.

The resulting map works fine with the Garmin hand-held navigators. Maybe it will work on your chartplotter...

Wow..

I am very interested to switch from Lowrance to Garmin. One of the main reasons I haven't done it yet is the maps I have created in RM over the years. If this works that would be great! Please keep us posted about the results of this conversion and if ithe maps work on Garmin!

The solution is interesting and work with handhelds as GPSMAP 60.

But is this a solution for newer Garmin units? I mean units with protection against own charts.

I will to test the ready file in my unit and if its not works, add the known trick against the protection for own charts.

But first: Thanks for such a solution, which create high quality map "for all"!

saw this link it looks interesting but how do you open in English?

Yes, among a large number of messages in Russian, it’s hard to find a valid link to the latest version of the program.

Here is a link to a folder containing the latest version of the converter and a folder with all previous versions of the program:

yadi.sk/d/TXiLsSBwJVO2mQ




The current version of the converter uses the old cGPSmapper as a compiler.
Therefore, do not wait for miracles in terms of compatibility of the charts (created by the converter) with modern Garmin chartplotters.

Tried this and got <filename>.kmz.mp(37): Error E017: Cannot parse coordinates.

Any ideas?

Do you need mapsource installed?

What file do you actually load onto your Garmin unit, the .mp file or the .img?

>got <filename>.kmz.mp(37): Error E017: Cannot parse coordinates

cGPSmapper can not parse coordinates in line#37 of <filename>.kmz.mp file.
Can you show this line ? ...Or attach the problem KMZ file ?

Try to convert .KMZ files from [test_maps] folder first.

> Do you need mapsource installed?

Yes. If you want to immediately see the result on your PC.
Also you can use Basecamp/HomePort.

Close these programs before converting!

>What file do you actually load onto your Garmin unit

Only GMAPSUPP.IMG !
Put this file in your device’s \GARMIN folder.

You can build great maps for Garmin from ReefMaster Data and Pictures, even 3D if you want ;)

BUT, it's a LOT of WORK... And you need some good knowledges...

Here are two screenshots from my Garmin Rino 530Hcx, of a bathymetric map that I've done...

BTW, after my map is done correctly, I install it in MapSource... Then, upload to the GPS...
