Should you need to reset the Nav and Audio systems on a Touring model, the Honda tech site says you need bot the vehicles VIN and serial #'s of the system itself. All I could find online was a reference to a registration card that was supposed to be in the glove box when I took delivery of the (new) car. Of course, it wasn't there, and the dealer was of no help. Does anyone have any ideas? Would appreciate any insight as to where I can find the S/N's.
