Product Description
The USA-630 is the latest step in Custom Autosound's quest for the perfect classic car radio. Its large OEM-style push buttons look right at home in a classic dash. Despite the classic look, it has modern features, including an iPod dock. You can browse your iPod by artist, song, album or playlist using the radio's buttons, so the iPod can stay hidden in your glove box or console. The USB input on the back of the radio lets you plug in a flash drive to play MP3 and WMA files.
The alphanumeric display shows song, artist and album titles when playing flash drive or iPod files, along with RDS station information. With the optional BluKit, you can stream music from a Bluetooth phone or player and skip songs using the radio's track-up button. The radio also mutes the music so you can take hands-free calls through it. With 300 watts peak, it should have all the power you need, and if you want more, four pre-out jacks on the back connect optional amplifiers. The back of the radio also has an auxiliary input for satellite radio or any portable player.

Suggested order for a 1974-1982 Granada

- Connect the antenna plug and the blue power-antenna lead if your car has a power antenna.

Tech tips for 1974-1982 Granada
- This radio is sold for the factory Granada opening used in 1974-1982 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.
