Does anybody have experience with custom maps on the Overlander?
My understanding is that custom maps work when using "Drive" mode but they don't work in "Explore" mode. Is there any way to use them in Explore mode?
If you come along this post because you're having problems with the Overlander. Start by updating GPS firmware to the current version. That may resolve some issues that you're having.
I have tried several options, but have yet to find a way to use other than Garmin map. One option is to sideload an Android app that to use in combination with the maps, but for most maps it will require an internet connection which I am trying to avoid.
