This started this morning. I did a reset of the unit, but it still persists. All other screens work fine. Only when I'm on the map screen does it only go to half screen. See pic. Any ideas?
Based on my experience using Dyna beads to balance motorcycle tires, I thought there could be a way to install a balancing device on the driveshaft based on the same principle.
I googled for 30 seconds and found that someone has actually made what I envisioned. Might be worth a try.
