I successfully used Navigation Updater in my Calligraphy, but now all the speed limit signs in my HUD, cluster, and screen are way off from the posted speed limits. In a 35 mph zone, the HUD, cluster, and screen show the speed limit sign as 48 mph. In a 40 mph zone, they show a speed limit sign of 64 mph, etc. I've double checked that all speeds in settings are in mph and not kph. The rest of the navigation, except ETA's computed on posted speed limits, is spot on, but it looks like Hyundai has a software glitch in speed limit zones. Re-downloading the update yields the same results. Any ideas how to overcome this glitch?
