Description
Custom Autosound's USA series puts modern audio behind a classic radio face in a 1967–1972 Chevy C10 or GMC truck. Every model is designed to fit the stock dash with no modifications required — the original dash and radio opening stay as they are. Four models are available, so pick the feature set you actually want.
Choose your model
USA-230
The more affordable radio in the range, without giving up quality electronics or the classic stereo look. It has the same appearance and features as the USA-630, simply without the USB port, iPod dock and CD changer control. There is an auxiliary input for iPods, iPhones, satellite radio tuners or any device with a headphone jack, plus 4-channel RCA pre-outs and a digital display with electronic tuner, 16 station presets and a 4-way fader.
USA-630
A bezel carrying your manufacturer's logo and large OEM-style push-buttons to complement the dash. A USB input plays MP3 and WMA files from a flash drive, and a dock handles your iPod — the digital display shows artist, song and album titles and lets you navigate songs from the radio. 300 watts peak, four RCA pre-outs for optional amplifiers, and auxiliary inputs for satellite radio tuners, iPhones or any portable player. Compatible with the optional BLUKIT for Bluetooth streaming and hands-free calling through the truck's speakers.
USA-740
Built-in Bluetooth with the microphone included, for answering calls and streaming music. 300 watts peak, Hi 4-volt 4-channel RCA pre-outs and a subwoofer RCA pre-out for additional amplifiers. The USB input plays MP3, WMA, FLAC and WAV files from a flash drive, and a front mini-jack plus rear RCA auxiliary input cover satellite radio, an iPod or any portable player. Selectable LCD colors with a dimmer let you match your instrument cluster, and the AM/FM RDS tuner shows station, song and artist. It also fully controls the optional CD-1 CD player.
USA-850
The DigaDial virtual screen radio gives you four distinct displays. Choose the classic '60s analog setting and watch the red needle glide across the dial, or the all-digital RDS display with station, song and artist information, in colors that match your instrument cluster. It adds 6-volt RCA pre-out and dual subwoofer outputs for external amplifiers, bass, treble and midrange control or DSP EQ settings (Flat, Classic, Pop, Rock), Bluetooth streaming and calls, USB playback of MP3, WMA and FLAC that also charges your phone, a rear RCA input, and support for the optional CD-1 single CD player.
