i been noticing my nav having to reroute itself consistently when i enter a destination. Last night, i tring to get direction to sonics and i was on the freeway, looking at the nav, it was showing me i was on the side streets and rerouting me turn around???

I thinking i need to recalibrate, is there a way to do this???

 

Hold both eject buttons and mute at same time until reboot and release. When fully awake, take 2-3 hard circles to the right then do the same for left.
