Hi. Thanks for the input, here in Bolivia we cant go any other way than Garmin, basically there is only one map available in electronic format and that one is the OpenStreetMap (OSM) (I am one of the editors).
Neither Garmin nor Tom-Tom have a official map of Bolivia (and several other countries of Latam)
The 5M-Baja looks very similar in form to the old Garmin 478 Gpsmap in the rugged sense. My vision is not so good and I want something with a big screen, that I could check quickly while driving.
Thanks and best regards
JJ
