The Dual XDM290BT is an AM/FM/CD/USB receiver designed for in-car audio entertainment. It offers a variety of playback options and features, including Bluetooth connectivity, MP3 and CD playback, USB input, and an auxiliary input. The unit is designed for a typical front-load DIN mounting method.
Preparation and Installation
Before installation, it is crucial to disconnect the negative battery terminal to prevent electrical issues. The unit should not be installed in locations subject to high temperatures, direct sunlight, dust, dirt, or excessive vibration. To begin installation, the trim ring must be removed, followed by two transit screws located on top of the unit. Supplied keys are then inserted into slots to slide the unit out of its mounting sleeve. The mounting sleeve is then installed into the vehicle's opening, with tabs bent to secure it. After this, the wiring harness and antenna are connected. It is recommended to consult a qualified technician if unsure about wiring. Some vehicles may require an additional installation kit and/or wiring harness adapter, which are sold separately. Once connections are made, the unit should be tested for correct operation before being slid into the mounting sleeve to secure it.
General Operation
The unit can be turned on by pressing the power button or any other button except EJECT, and turned off by pressing the power button. The MODE button allows selection between various audio sources: AM/FM, CD player, auxiliary, USB, and Bluetooth. CD and USB modes will only appear if a CD is inserted or a USB device is connected.
For external audio devices, the XDM290BT features a 3.5mm auxiliary input port on the front panel. To use this, the MODE button is pressed to select auxiliary input mode. Volume is adjusted using the volume knob, with a range from 00 to 46. The DISP button shows the clock and, during MP3 playback, rotates through ID3 tag information, elapsed time, track number, and file/folder names.
If abnormal operation occurs or after initial installation, the RESET button, located under the volume knob, should be pressed. To set the clock, press and hold DISP until the clock flashes, then use the TUNE buttons to adjust hours and minutes. The clock displays 12-hour AM/PM time in USA frequency spacing mode and 24-hour time in European frequency spacing mode.
Audio Controls
The volume knob can be pressed momentarily to access audio control settings, including Bass, Treble, Balance, Fader, EQ, Loudness, and Source Level. Each setting can be adjusted by rotating the volume knob left or right once the desired option appears on the display. Bass and Treble can be adjusted from -6 to +6. Balance can be set from BAL 7L to BAL 7R, with BAL EVEN indicating equal balance. Fader can be set from FAD 7R to FAD 7F, with FAD EVEN indicating equal fader. EQ settings include USER, ROCK, BEAT, CLASSICS, JAZZ, POP, and FLAT. Loudness can be toggled OFF/ON. Source Level adjusts the current source volume from -6 to +6.
The setup menu is accessed by pressing and holding the volume knob for more than 3 seconds. Within this menu, the volume knob is used to select functions and adjust settings.

Dual iPlug P2 Smart App Remote Control
The Dual iPlug P2 Smart App allows control of the receiver via Bluetooth from an Apple or Android smartphone. This app enables changing mode, station, song, volume, and settings without line-of-sight. The app can be downloaded from the Apple App Store or Google Play Store.
Voice Activation
The receiver has an easy-access voice activation button to use Siri® or Google Assistant™ via Bluetooth. After pairing the smartphone with the receiver, pressing the voice activation button switches the receiver to Bluetooth mode, activating the smartphone's assistant. Manual switching back to the previous or desired mode is required after the operation.
Maintenance
For troubleshooting, if the unit has no power, check connections for proper voltage (11-16VDC) for the yellow and red wires, and check the ground connection for the black wire. Replace blown fuses. If there is power but no sound, check speaker connections and ensure no bare speaker wires are touching each other or chassis ground. If the unit blows fuses, check for pinched yellow or red wires, pinched speaker wires, and ensure the correct fuse rating is used. For excessive skipping, ensure the unit is mounted correctly and the backstrap is secure. Check media for physical defects. If "ERR FILE" appears, press eject or RESET. If "NO FILE" appears, check the device for valid MP3 files. If the unit does not accept a disc, check for CD mechanism misalignment and ensure transit screws are removed. If "NO SUPPORT" appears, an invalid ID3 tag version is present (only versions 1.0 to 2.0 are supported).
For optimal MP3 playback, it is recommended to burn MP3 discs with a 128kbps or higher constant bit rate and 44.1kHz or higher sampling frequency. Some files may not play or display correctly depending on sampling rates and bit rates. Only MP3 files with the .mp3 extension can be played. USB devices must be 'mass storage class' and formatted to FAT or FAT32 file systems for compatibility.
