How do I pair my phone via Bluetooth?

Turn on the device and enable Bluetooth on your phone. Search for 'MD-160 BT' in your phone's Bluetooth settings and select it. Enter '0000' if prompted. The connection is established when the display shows 'BT' and your phone name.

What to do if the stereo does not power on?

First, check the vehicle's fuse for the radio circuit. Ensure the wiring harness is properly connected (constant 12V, ACC, ground). If the fuse is blown, replace it with one of the same amperage. If the problem persists, consult a professional.

How can I reset the device?

Press and hold the reset button (located behind the front panel or on the front, often a small hole) using a paperclip for 5 seconds. This restores factory settings. Alternatively, disconnect the power for 10 minutes.

Can I use a USB drive with more than 32GB?

The device supports USB drives up to 32GB formatted in FAT32. Larger drives may not be recognized or may cause playback issues. Use a high-quality USB 2.0 drive.

How to set the clock?

Press and hold the 'MODE' button until the clock starts flashing. Use the volume knob or seek buttons to adjust hours and minutes. Press 'MODE' again to confirm.

Why is there no sound from the speakers?

Check if the mute function is active (press and hold the volume knob). Ensure the volume is turned up. Verify speaker wire connections at the stereo and speakers. Also check the fade/balance settings.

Does this unit support steering wheel controls?

Yes, the MD-160 BT has a wired remote input for steering wheel control adapters. You need to purchase a compatible adapter (e.g., Auna SWC-1) and connect it according to the adapter's manual.

Can I connect an external amplifier?

Yes, the unit has RCA preamp outputs (front, rear, subwoofer). Connect the amplifier using standard RCA cables. You may need to enable subwoofer output in the settings.

What is the maximum power per channel?

The maximum output power is 45 watts per channel (4 channels total). RMS power is approximately 15 watts per channel. Use speakers with an impedance of 4-8 ohms.

How to update the firmware?
