dmdt gs
With just internal MIB main screen (G13 9.2''):
with MIB main screen (G13 9.2'') and VC connected:

displaymanager reports the following system information:
number of displayables: 7
number of displays: 2
display 0:
name: display0
terminal: main
size: 1280 x 640
context id: 1

display 1:
name: <error>
terminal: <error>
size: 0 x 0
context id: 70
33 (DISPLAYABLE_KOMBI_MAP_VIEW)
VC is listed as display 1 with no seize (0x0)
However, test have shown, that VC seems to be also refereced by display 4
which allows for certain manipulation based on the commands below.
dmdt dc
more testing needed
dmdt sc
| Command | screen |
|---|---|
| /eso/bin/apps/dmdt sc 0 70 | VC map |
| /eso/bin/apps/dmdt sc 0 71 | Smartphone |
| /eso/bin/apps/dmdt sc 4 -9 | mirror screenshow to VC |
Other combinations did not work for me - either nothing happens or screen goes black
If stuck on black/purple screen, it can be recovered with dmdt sb 0
VC map output
3rd screen from the upper left is the VC map view
Take screenshots via console command
Screenshot from main screen on Unit:

Functions have to be tested.
There are some more ascii strings to explain start command in binary

using the script below *.png/bmp/jpg/gif/tga can be displayed on screen

Android Auto screen output
AA is directly streamed as a h264 video stream from usb to screen.
In /etc/eso/production/gal.json video dump can be enabled and in /tmp files like AAPDumpVideoSink_1970-01-01_12-12-25.h264 will be crated, which can be converted to mp4 and viewed in vlc etc - recording a full screen view of everything that happens:
Due to this video streamin dmdt sc and also screenshots do not have any effect as its seems.
