Is there a way to reset or clear the navigation system and the radio presets? I want to remove the navigation history and reset the "home" designation.

 

Yes there's a way - but it would reset all of your settings to default including any set for the vehicle.

It should be under options somewhere, titled something similar to reset "Personalized Settings".

I wish I could give it to you from the top of my head, but that's all I can remember, sorry
