GPSMAP 66st software 4.20, GPS 2,80.

Start from the map page (regular map display).
Press menu -> Map setup -> Configure maps.

If you have many maps and some BirdsEye images the BirdsEye Sataellite imagery is the last map shown in the list.
Normal maps have an enable/disable switch. BirdEye has menu with four positions which open when enter is pressed.
When the BirdEye map is at the very bottom, only three of the four options are visible.
The last option to Disable the maps, is below the screen, it can be moved to using the D-pad and the maps can be disabled, but would be nice if if was on the screen.

I was not able to find the issue in the common issues page, but if it is duplicate, please remove this thread.

Can you take a screen capture and post it here, please?

Screenshot of the menu Disable option not visible.

Fascinating. Thank you for posting the image!

Please retest and advise after installing the next firmware update on your GPSMAP 66.

Garmin express just updated the unit to software 4.70, but again without any release notes. I am in Europe and guess it will be available soon every where else.
This particular issue is still present.

Very strange. We also have v470 installed, but can not duplicate this issue.

Can you try a different profile and see if it still behaves this way? Perhaps a profile you have not changed much?

Hi.
The profile does not change anything, i tired with untouched profiles.
However, the more maps (.img) files i add to the SD card, the fewer lines i see in list.
When the menu showed 3 out of 4 items i had a total of 19 items under the Configure Maps (including one row for custom maps, and one for the BirdsEye).
When i now have 22 items, i cannot see any of the items on the menu which should be visible.
It seems to be a limit somewhere around 18-20 maps, but i don't know the exact limit yet.

Ahhh.

Are you certain you have not surpassed the 15k map segment limit with all those maps?

We will have to find more maps to load and test on our unit to see if we can duplicate.

We have duplicated this behavior!

With 17 *.img maps loaded, plus any number of *.kmz maps, all BirdsEye Satellite Imagery options are available in the Map page configuration menu.

With 18 *.img maps loaded, plus any number of *.kmz maps, one BirdsEye Satellite Imagery option is unavailable in the Map page configuration menu.

With 19 *.img maps loaded, plus any number of *.kmz maps, all BirdsEye Satellite Imagery options are unavailable in the Map page configuration menu.

This will be posted as Bug #91 to GPSrChive > GPSMAP 66 > Common Issues.

Please report this to Garmin Support, and ask for a case number!

This may be related: with firmware 4.20, I found that the device can only list 20 IMG files across the internal memory and microSD card. If you upload more than 20 IMGs, you cannot see the others or their toggle switches. Haven't tried this with 4.70 yet.
