The RetroSound® Hermosa RetroRadio™ retains the original look of your classic 1977-83 Oldsmobile 98 while offering the most modern features available. Hermosa has built in Bluetooth® wireless connectivity, so you can safely make hands-free telephone calls through your audio system and also stream music from any smart phone.
The Hermosa features an AM/FM tuner. A rear mounted USB port allows you to play MP3/WMA/FLAC music files through your system using up to a 32GB flash drive, which is enough space for as many as 7000 songs. Two rear mounted auxiliary inputs for portable devices are also included. Featuring a 32,000 color display, that lets you customize the Hermosa to your vehicle's interior. A built-in 300-watt amplifier (25 watts RMS/45 watts peak x 4 channels) provides plenty of power to your speakers, and dual RCA pre-outs let you add external amplifiers.
Hermosa uses the patented InfiniMount adjustable shaft system to make installation easy in virtually any classic car or truck. For added custom installations, Hermosa’s radio body may be mounted remotely using the optional extension cable.
