Features

Infinimount Shaft/Bracket System: The Infinimount Shaft/Bracket System allows you to mount the RetroRadio (M1B) radio in a variety of classic cars. This is because the shaft-knobs are not mounted to the unit, but instead connect to the unit via a harness so you can space the radio's shaft knobs at various distances (0.3125"-2.1875") from the chassis of the radio, using the supplied side-mount brackets. You can move these brackets forward or backward and move them in any direction. You can even cut, trim, or bend the brackets if needed. This shaft-style radio is a true problem solver for tough to fit applications due to its unique bracket system combined with small mounting size.

Faceplates & Knobs (sold separately): There are multiple vehicle specific faceplates & knobs available for the RetroRadio (M1B). In addition there are universal faceplates which allow you to use the integrated break away tabs to modify all aspects of height & width of the plate, and even drill in your own shaft holes to fit virtually any car.
