National Auto Sound Map:

Please note, our address does not place properly in some navigation software because of the way Highway 40 is numbered.  Navigation systems will put us in a wrong location. The above National Auto Sound map is correct. To avoid problems, we recommend putting in the nearest intersection into your nav unit and you will find us easily:  we are just west of the intersection of Sterling Ave. & US Highway 40.  We are on highway 40, just down the hill from Quick Trip and right next to V’s Italian Restaurant. We are on the south side of Highway 40.
