Garmin TOPO Active v OS mapping

Tue 25th October 2016

TopoActive mapping – This is mapping based on open source maps and therefore it has some map data in there so it gives you turn by turn data (like a car satnav). View those units here.

Many of the other GPS units come bundled with 1:50k and 1:25k Ordnance Survey Maps – This is the most popular as it is a micro SD card that sits in the back of the unit. View those units here.

So what are differences in these map sets?
