The Caliber RMD 035DAB is a car radio featuring FM/DAB+ radio, Bluetooth connectivity, and USB/SD playback. This guide provides essential steps for installation, wiring, and daily operation.
Installation
The unit is designed for a standard dashboard mounting sleeve. If necessary, bend the metal claws on the sleeve outward for a tighter fit. To remove the main unit, insert the provided keys into the holes on each side between the unit and the sleeve.
DAB+ Antenna Installation
For optimal DAB+ reception, the included screen-mount antenna must be installed correctly. Place the antenna on the windshield near the A-post. Remove the A-post cover, stick the transparent part of the antenna to the glass, and attach the black part to the metal frame. The antenna is powered through the antenna wire core (+5V), so no separate power connection is required.
Wiring Diagram
The unit uses a standard ISO connector. Key connections include: A4 (Yellow): Battery+, A5 (Blue): Antenna out, A7 (Red): ACC (ignition switch), A8 (Black): GND (battery-). Speaker outputs are provided on connector B (B1-B8).
Operation
Use the MOD button to switch between FM, USB/SD, AUX, Bluetooth, and DAB+ modes. Audio settings (Bass, Treble, Balance, Fader, Equalizer, Loudness) are accessed by pressing the VOL knob. RDS settings (AF, TA, REG, EON, PTY) are accessed by long-pressing the VOL knob.
Bluetooth
To pair, switch to Bluetooth mode, search for CALIBER_RMD035DAB on your phone, and enter password 0000. Once connected, LINKED will appear on the display.
USB/SD Playback
Insert a USB or SD card to start playback automatically. Use the number buttons (1-6) for playback controls (Play/Pause, Interval, Repeat, Random, Folder selection).

Low volume from auxiliary device
Increase the volume on the external device (phone/MP3 player) to ensure proper signal levels.
