I don´t have old OSM data. But I tried bounding boxes from very different parts of the world. Even tiny maps with only one tile do not work. It´s very unlikely that there are new errors in OSM data all over the world that can cause this problem.
Rumors say that Garmin wants to block several third party marine maps in their latest firmware.
Users already found a way to downgrade their devices to make OSM maps work again (Garmin says, downgrades are not allowed):

Hi Jürgen,
I did not download that old map because I have no idea what to look for.
Maybe the problem is in the OSM data, not in the program?
Do you have a backup of an older *.pbf file to try that?

Thank you Gerd for your very fast reply.
Is it really enough to exchange just the mkgmap.jar but keep the libraries to completely go back to r3316.
Unfortunately I was not able to find the problem, yet. If I make maps with this mkgmap-r3316 they do not run on any current marine device with firmware 4.00 or 4.20. I made maps using my style and my options but also with default style and default options.
No matter what I try, there will be the “map not supported” message on the Echomap 50s.
But amazingly this old map, I made with r3316 in 2014 runs perfectly:

Hi Jürgen,
see link below. The jar file contains also the style files.http://files.mkgmap.org.uk/download/246/mkgmap.jarGerd

Dear list
Garmin recently released a major firmware update (v 4.0) for the Echomap and newest GPSmap marine series.
After the firmware update my current charts fail with a “map format not supported” error on those devices.
However one of my old charts which was produced with mkgmap-r3316 in mid-2014 still works.
I want to track down the problem. Can someone point me to a download-link for mkgmap-r3316 (both binaries and default style from this release) so I can try to reconstruct a map that does not produce the error?
Regards
Jürgen
