Topic: not more than 3 raster image maps on Solix 12

[emerles]

I use a Helx 7 and a Helix 10 on my boat.
My friend uses a Solix 12 Chirp Mega SI+ G3.
We have created some maps of our local lakes that we fish.
I can create a lot of raster image maps with AutoChart for my Helix 7 and Helix 10 and can also select them from the menu on the sonar.

My friend can also create more than 3 maps (raster images) with AutoChart.
He has named the raster image maps “image (1)”, “image (2)” and “image (3)”.
But, if he creates a fourth raster image map named “Image (4)”, the map is not selectable from the sonar menu.

Is there an option or configuration switch to expand the maximum number of raster image maps to more than three on the Solix?
