Audiotek AT-990BT Single DIN CD/MP3 Receiver

The Audiotek AT-990BT is a Single DIN in-dash CD/MP3 receiver for vehicles that need straightforward music playback, radio reception, and Bluetooth connectivity in one compact unit. It supports physical discs as well as USB drives and memory cards, giving drivers multiple ways to access a music library. A front auxiliary input adds a wired playback option for compatible portable devices.

This receiver is suited to drivers replacing an older factory radio or building a basic audio system around conventional four-channel speakers. Built-in Bluetooth supports wireless audio streaming from a compatible phone or device. The AT-990BT does not list Apple CarPlay or Android Auto capability, so device navigation and app interfaces remain on the connected phone.

Its published output rating is 50 watts maximum per channel across four channels. Electronic volume, bass, treble, balance, and fader controls provide practical adjustment for the vehicle and speaker layout. RMS power output, speaker-load rating, and amplifier distortion specifications are not published for this model.

The AT-990BT combines CD playback with MP3 and WMA file support, plus USB, SD, and MMC media compatibility. Repeat, random, and intro playback modes help manage stored music, while last-memory operation can resume a previous playback position. A built-in high-sensitivity FM receiver and preset scan function provide broadcast-radio access.

For system expansion, the receiver is listed with four-channel RCA outputs for connection to compatible external amplification. Its detachable face panel, digital clock display, and infrared remote control add everyday convenience. This makes it a practical choice for an older vehicle that benefits from multiple media sources without adding a touchscreen receiver.

Confirm that the vehicle accepts a Single DIN receiver before purchase, then use the correct vehicle-specific dash kit, wiring harness adapter, and antenna adapter as required. Connect the vehicle wiring according to the receiver's supplied wiring information and insulate all connections securely. Use the rear four-channel RCA outputs only with compatible external audio equipment, and verify the vehicle's speaker wiring before powering the receiver.
