Product Description
The 1957-58 Oldsmobiles carried the Rocket V8 in long, chrome-trimmed bodies. This Custom Autosound USA-230 is the 1957-58 Oldsmobile version, made to keep a classic look in the dash while adding modern features.
Fit and Ordering
This listing is the 1957-58 Oldsmobile version of the USA-230, made for the factory radio opening. Confirm fit for your model before ordering.
What Makes It Different
The USA-230 shares its look with Custom Autosound's USA-630, but it skips USB and CD changer control. What you get is a clean, dependable AM/FM stereo with presets, a clock and an auxiliary input for your own music, at a lower cost than the more feature-packed models.
Keeping the Dash Original
The dash is one of the first things people notice in a classic. A radio built to fit the factory opening keeps it looking right, protects the value of the car and avoids permanent changes, while still giving you the convenience of modern sources.
Feature List
- 4-way fader
- Digital clock
- Power antenna lead
- AM/FM stereo with an electronic tuner
- 16 presets (12 FM and 4 AM)
- 200 watts (50 watts x 4)

Complete Your Order
- Front dual voice coil speaker, which plays both stereo channels through a single dash speaker
- Rear 6x9 speaker pair, Custom Autosound or upgraded Pioneer

Connect Your Phone
The rear 1/8-inch aux input carries music, podcasts and navigation prompts from your phone to the car's speakers.
Warranty
This Custom Autosound radio is covered by a 2-year warranty.
Getting the Best Sound
Start with fresh speakers and good wiring. Old paper cones and corroded connections hold back even a great radio. Set the bass and treble modestly at first, then adjust for your cabin; open cars and trucks usually need a little more bass than closed coupes and sedans.
Before You Install
The radio needs a 12-volt negative ground system. Many older vehicles were built 6-volt or positive ground, and Custom Autosound makes converters for both situations. Ask us if you are unsure what your vehicle has.
Disconnect the battery before you start, check the old wiring behind the dash for brittle insulation and use a fused feed with a solid chassis ground. A qualified auto sound shop can handle the job if you prefer. Vintage Car Radio sells the radio and accessories but does not offer installation.
Fit Questions
Dashes changed often, even within a model line. If you are unsure which version you need, have your year, model and any dash changes ready when you contact us.
Amplifier Ready
The 4-channel RCA pre-outs make it easy to add an amplifier for more power or a subwoofer for deeper bass, without replacing the radio.

Suggested order for a 1957-1958 Oldsmobile
- Disconnect the vehicle battery before any wiring.
- Connect ground first, then constant (yellow) and ignition (red).
- Connect the antenna plug and the blue power-antenna lead if your car has a power antenna.
- Wire all four speakers, matching polarity.
- If using an amplifier, run RCA cables from the front/rear (and sub on USA-740/USA-850) pre-outs.
- Reconnect the battery and test radio, speakers, and charging system voltage.
Tech tips for 1957-1958 Oldsmobile
- This radio is sold for the factory Oldsmobile opening used in 1957-1958 models—do not cut a modern DIN rectangle if you want a stock look.
- A poor ground is the most common cause of whine or weak audio; scrape paint at the ground point and use a star washer.
- If AM reception is weak, check the antenna mast, cable continuity, and that the antenna plug is fully seated.
- Vintage Car Radio does not install radios. If you are not comfortable with 12V wiring, use a qualified installer.
