[mkgmap-dev] Maps no longer working after firmware upgrade?

From Felix Hartmann extremecarver at gmail.com on Fri Nov 16 16:48:43 GMT 2018

are you sure you're not sending maps with MapInstall 4.2.0?
Meaning are you sure you did not destroy the .img files using Mapinstall
4.2.0? Use mkgmap itself to generate a gmapsupp.img (of a non unicode map
just to be sure - maybe the firmware update crashes unicode maps but I've
not heard of that for etrex 20/30)  and check if that works.
Can you not downgrade the firmware?
