Garmin Zumo 220 not seeing GPX routes/tracks

So i've recently goten my hands on an old Zumo 220 unit to mount on my motorcycle for off-road adventures. I've connected the unit to Basecamp and imported two GPX tracks, but the Zumo absolutely does NOT wanna see them, it recognizes the waypoints/POIs from the track, but that is it. Have tried cconverting to route, but no luck at all. Have also tried just copying the GPX file straight into the GPX folder onto the unit, but to no avail. Any help would be appreciated.
