I don't have a solution as I have not played with this specific device, now we know which maps it might be worth trying changing the CP value on the Europe NTU maps as it works on older Android devices

Thank you! I will try to modify the map as you suggest!

Edit : I used your advice and partially solved the problem. Dezl read the modified OSM map, but refuses to read the modified map from Garmin.

Welcome to the forum.
Atemos 100 | 2894 | 330 | MAP: Yes | GMA: Yes | MSV: Weak | GVS: --- | File: Atemos100_330.gcd

Legend:

MAP: Yes - it verifies the presence of a valid unlock code, to unlock an .img you can simply use JetMouse keygen.
GMA: Yes - it verifies the FID limit (2200) and the presence of a valid *.gma, to unlock an .img you enough to use the old gimgunlock-0.03 (without MapSigPatch) or one of its derivative.
MSV: Weak - it verifies the validity of map signatures in a simple way, you can unlock an .img using gimgunlock-0.04 (without patching your firmware), but in case of unicode maps (CP65001) you must modify the CP value (see the Temporary authentication of Unicode maps*).
MSV: Strong - it verifies the validity of map signatures more complicated way, in this case you need to patch your firmware and unlock an .img using any correct unlocker.
GVS: Yes - it verifies the validity of firmware signatures, you have to use Updater.exe to install the patched firmware for the first time.
