Most CD-capable car receivers play compressed and lossless formats commonly found on discs and USB drives, including MP3, WMA, AAC, WAV, FLAC and Vorbis.
CD-capable receivers commonly include built-in Bluetooth for hands-free calling and streaming, support Apple CarPlay and Android Auto (some models offer wireless CarPlay/Android Auto), and provide USB ports or USB mirroring for wired phone connections.
Most mechanisms are compatible with standard CD formats: CD, CD-R and CD-RW. Some double-DIN multimedia units also list broader compatibility, including DVD formats for video-capable models.
Typical CD receivers offer a front auxiliary input and one or more USB ports, plus multiple line-level outputs (often three pairs for front/rear/subwoofer) and preamp outputs—many models specify a 5.0V pre-output level.
Car CD receivers are usually available in single-DIN and double-DIN sizes to fit standard dash openings.
Many listings show maximum speaker output around 50W x 4 and conservative full‑bandwidth ratings near 22W x 4; preamp (pre‑output) voltage is commonly specified as 5.0V.
Multimedia units frequently provide multiple camera inputs (examples often list 3 or 4) for front, rear and side views, plus dedicated front/rear camera inputs and video output connections.
