Is there a way to download the Garmin Topo 100k maps to the Overlander?
The Overlander has 24k Topo maps installed when you purchase it, so you would have to purchase the 100k Topo map, it has been reported that 100k Topo maps can be installed to this unit https://support.garmin.com/en-GB/?faq=QKKYuoFg5L9D8Nv5wW6Pg5 https://support.garmin.com/en-GB/?faq=Xk377kzvYw81i2ymEv5de7 If you have a lot of installed maps already on your Overlander you may have to select a smaller section of the main 100k Topo map so that it will fit onto the 64GB internal memory space as Topo maps can't be installed to microSD cards on the Overlander
