[mkgmap-dev] Maps no longer working after firmware upgrade?From Ticker Berkin rwb-mkgmap at jagit.co.uk on Fri Nov 16 17:13:32 GMT 2018
couple of thoughts I've experienced the devices remembering parts of the map structure and being in a bit of a mess when I've used the same map but copied to a differently structured SD card. Maybe the newer firmware has a different idea of the internal structures. So, suggest you make a new map and try that, rather than one the device has seen before. I got a new Etrex 30x a few weeks ago and upgraded the firmware from 2.50 (as installed on purchase) to the latest: 2.90 (using the garmin quickstart windows program). I've not had any problems with mkgmap generated maps.
