The 1957-1958 Buick Roadmaster USA-740 radio is our top of the line radio. The CAM-RMAS-78-740 features an AM/FM digital tuner, Bluetooth built in, a USB port, two auxiliary inputs, and the ability to add a CD player with the CD-1 single disc player. This 1957-1958 Buick Roadmaster radio from Custom Autosound and allows you to listen to the radio, stream music from your phone and talk hands free without having to cut the dash of your 1957-1958 Buick Roadmaster. Custom Autosound is the leader in the classic car radio industry and this radio does not disappoint.
The USA-740 1957-1958 Buick Roadmaster radio has Bluetooth built-in so that you can wireless play the music from your phone through the speakers in your classic car. You can use Spotify, Pandora, Apple Music, Podcasts, or whatever other audio apps you like including the Sirius XM app, if you are a subscriber. In addition to Bluetooth streaming, the USA-740 also comes with a microphone so that you can obey the laws and talk on your cell phone, handsfree.
The 1957-1958 Buick Roadmaster USA-740 radio has a digital tuner like virtually all radios today so you don't need to worry about the station bouncing due to vibrations or bumps in the road. For the AUX inputs, there are two. There is a 3.5mm stereo jack in the lower right hand corner of the radio face and there is an RCA AUX input on the back of the radio. Like the USA-630, the USA-740 has a USB port on the back of the radio. The USB port will play songs off of a thumb drive and will charge your devices, but the USB port does not support audio playback from your devices.
The USA-740 puts out 300 watts of peak power to 4 channels. This is the same output as the USA-630 and the Slidebar radio, and more power than the USA-230. If you want truly amazing sound, add an amplifier. If you want the best sound quality without an amplifier, this is the way to go.
If you still have a listen to CDs, you can add the CD-1, external CD player and plug it in to the back of the 1957-1958 Buick Roadmaster USA-740 radio. The CD-1 is a 1/2 DIN size device that measures 7" x 1" x 7" and includes a 10 foot cable. Typically, the CD-1 is mounted under a seat, in the glove box, under the dash, in the trunk, in a custom console, or anywhere else it may fit in the interior of your 1957 Chevy.
If you want to add an amplifier, the USA-740 1957-1958 Buick Roadmaster radio comes with 4 channel pre-outs for the speakers as well as a subwoofer pre-out and subwoofer control on the radio. If you want to add a 4 channel amplifier, simply ignore the subwoofer pre-out. But, if you want to add a 5 channel amplifier, connect the subwoofer RCA cable to the pre-out on the back of the radio and you can control the subwoofer level directly on the radio. We still recommend a bass knob because it's faster and easier, but if you don't want to deal with the bass knob, the subwoofer control works well too.
You can change the color of the diplay on the USA-740 to match your vehicle's exterior color, interior color, or the color of the rest of your interior lights. This is perfect if you have Dakota Digital gauges or something similar. You can ensure that the radio display matches the rest of your interior lights. In addition to the multi-color display, this radio also allows you to select the brightness of the LCD display on the radio beetween 0-7. Everyone has a different tolerance for brightness when driving at night and this allows you to set the brightness to the ideal setting for your eyes.
If you want a Bluetooth radio in your 1957-1958 Buick Roadmaster, this Custom Autosound USA-740 is the way to go. It has more features than the USA-630 and you don't need to purchase an external adapter to get Bluetooth functionality.
For installation, the USA-740 1957-1958 Buick Roadmaster radio comes out of the box ready to install. You do not have the assemble the radio yourself. The shafts have already been set to fit the stock dash opening and the nose piece is already connected. You don't have to put it together, set the knob spacing, set the knob height, test fit, or potentially scratch your dash while assembling the radio for installation.
Because the radio arrives pre-assembled, it makes installation faster and easier so that you can get back out on the road and drive your classic car and without a headache.
If you are not installing it yourself and instead are paying someone to install it, it's one less hour (or sometimes two) of labor you have to pay for.
While working on classic cars is fun, we do it so that we can go out and drive them. This radio gets you cruising in your favorite vehicle, listening to your favorite tunes, with a big ol' smile on your face in less time, with a lower total cost.
We stand behind the products we sell and so does Custom Autosound. All USA-740 radios come backed by a 2 year warranty.
