Nice job by marc, i downloaded and will try it in future, and report in his thread, if find some bugs ...
And to inform all people included in this thread, problem is finally solved, our friend lolly helped me with his nice suggestion to use gimgunlocker for unlocking all newer maps, even AR 4.10 has lower FID 708 than 2200, GarminUnlocker showed that unlocked AR 4.10, but it seems like lolly noticed there was some errors in headers.
Now original CN maps which came on device originally from Garmin shop can coexist with AR 4.10 on SD card , and in mymaps menu can be selected which one we want to use , cause now are 2 maps, primary - on internal memory, and supplement map on SD CARD !
Thanks to all of you, who helped to solve this "mistery", which caused GarminUnlocker.exe with errors on map with FID 708 , specially to lolly ! So this thread can be closed , case solved .
