I'm looking for advice on a navigation device. This will be used primarily for bikepacking and the handful of races I enter each year. The races are typically gravel/fatbike events on forest service roads or snow machine trails. Most are not marked, but a GPX file is available. I like simplicity, ease of use, something intuitive. It seems many bikepackers use the Garmin eTrex 30, now the 30x. Advice appreciated.
