This listing is for the shafted version of Redondo, only. If your vehicle came with thumb-rollers, you will need Redondo RT.

The RetroSound® Redondo is a modern radio with the classic look for your 1971-75 Plymouth Duster. Redondo features separate radio display and push-button assemblies that are independently adjustable thanks to RetroSound's patented InfiniMount system. This is the most technologically advanced radio ever produced for your vintage 1971-75 Plymouth Duster. This radio listing features period-correct metal knobs and our chrome faceplate with a matte grey center finish. Redondo looks like the original factory radio but includes all the features of a modern car stereo.

The Redondo Hermosa comes standard with a powerful built-in 25 watts RMS x 4 channel amplifier, and RCA pre-outs are provided for adding external amplifiers. It features built-in Bluetooth® for hands-free calling and wireless audio streaming — and Bluetooth® Music Browsing. Redondo has a 32,000 color display allowing it to be customized to match your vehicle’s interior.
