What's my best option, Montana, 590 or 700i
I'm intending to set off for Africa in spring 2023, in the past I've used paper maps, which I love but are heavy because of the number needed for this trip. I have an old Garmin 590, a Montana 6 series and an iReach. I know that it's all old school, but they still work. The alternative is to buy 700i, but apart from having a more compact set up, I don't know if there is any real advantage. Probably gathered that on this type of tech' I'm a bit of a numpty. Also can any of these be loaded with such as OSM?
