New tech with classic good looks
RetroSound's Hermosa M2A digital media receiver matches the look and fit of the factory radio in your vintage vehicle, yet provides Bluetooth® for hands-free calling and audio streaming, a USB port for digital media, and inputs for other portable music players in your classic ride. You can mount this receiver in almost any classic car, using an ingenious adjustable shaft system that adapts to any dash opening. And the Hermosa is available in an assortment of finishes, so you'll have a perfect match for your classic car's interior.
Hands-free calling and digital sound
You can use built-in Bluetooth to talk hands-free or stream audio programming from your smartphone to the receiver, and you can also plug a USB thumb drive into the rear USB port for listening to your digital music. You'll find two auxiliary inputs on the rear of the receiver for other sources, like a satellite radio or hi-res portable audio player.
The Hermosa M2A also offers excellent AM/FM reception for all your local stations. This RetroSound receiver features two sets of preamp outputs that make it easier to add amps and subs to stand out at the next car show. For some customization, you can choose from 32,000 backlight colors so the LCD display will look just right in your dash. And for some more vintage goodness, you can even purchase dial screen overlays for the Hermosa M2A to accentuate the look in your ride.
Make it a complete RetroSound system
Wanna add some serious power to your ride? RetroSound offers strong amplifiers to get the most impact out of your speakers and subwoofer. They also make low-profile car speakers that fit into a wide range of older cars and trucks, so you can be sure that your sound system will do justice to your vintage vehicle.

More details on the RetroSound Hermosa M2A
Infinimount Shaft/Bracket System: The Infinimount Shaft/Bracket System allows you to mount the Hermosa (M2A) 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 Hermosa (M2A). 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.
