the other day, I was skimming the owner's manual for the NavSys when I came across a brief mention of there being a recalibration feature built in that you can use when you change tires. Anybody knows exactly what that does? I would imagine it could introduce a GPS-derived correction factor for mileage on the NavSys side of things, although, that does not seem obvious to do. Conversely, I would doubt it would affect the odo and speedometer on the dash, those probably are kept separate.
So anybody with bigger tires has ever tried to see what that does and figure it out?
