This Android device does not have the Firmware that can be patched with this Patcher

Thanks, GarmanNuvi!
Is it a dead end? What can you advise ?
Second question, analysis shows that the device seems to see only NTU format cartography exclusively.
Unfortunately, it does not see my hand-made maps in MPC-format. Do you know a recommendation for me?

This is the future of Garmin devices

N & S America, South Africa ,Australia & New Zealand are all NT

Convert and try or ask Garmin about third party maps

what is your Garmin Overlander's ID

Please do not ask for a members device's ID
