Maps corrupted during update. can't restore via MyDrive Connect
went to take a charger to keep it on a charger during update proces.
plugged it in, started the update, after a while came to check on it.
now the maps are corrupted, so followed the guide / video to try and recover them.
for some reason i can't recover/ reinstall the maps, tried different 16gb external micro sd cards. one got recognized just once, after that not anymore.
so i'm stuck with a device that does not have a map and thus not useable (would not have been a big issue before, but i switched jobs and my new truck does not have an navigation build in).
please help me out on this one as i've been trying for 2-4 hours the last 2 days to get the 620go truck navi to work again.
best regards and many thanks to all
