My compass on the navigation (Arrow) upper left corner is spot on, however I noticed the compass on the information display between the speedometer and tach is way off. I will be driving dead south and it says SSE or SSW. I had the MDX battery replaced under warranty and noticed this problem after that repair. Does anyone know if it can be calibrated? I cant seem to find it in the owners manual, it does show something but I think its for non navigation models. Thanks everyone.
