I just found recently that my Sonar Viewer software stopped showing the map. In the Map View window, it only shows the sonar tracks with a blank background but no base map. I am using the lastest version which is v1.0.38.0. and I have the same problem for both of my two computers

Thanks, looking into it.

Thanks. Just curious if you have the same problem.

Yes, there was a change with our map service provider which we were not aware of. The Sonar Viewer has now been updated and you should be prompted to udpate the next time it is started. Please let me know if this resolves the issue for you.

Thanks a lot! it works now with the new update.

Hi,
I have the same problem, the world map is not displayed.
Version 1.8

This is a known issue with ReefMaster v1.8, due to the fact that our map provider has changed the way that maps are downloaded. RMv2, the Sonar Viewer and the Waypoint Manager have all been updated to use the new method. RMv1.8 has now reached end of life and is no longer receiving updates. If you want to continue viewing base maps, you will need up to upgrade to RMv2. Sorry I can't be of more help on this one.

Thanks Matt.
