Make sure you have properly paired and
connected your Bluetooth device.
Make sure you have properly connected the
Bluetooth antenna to the terminal on the rear
panel.
Improve the Bluetooth signal reception by
moving your Bluetooth device closer to the
unit. Also, remove obstacles (walls, furniture,
etc.) so there is a clear line of sight between
your Bluetooth device and the unit.
Enter 0000 as the PIN. (Some older Bluetooth
devices may require you to enter a PIN.)
Disconnect and reconnect the USB device or
SD card to make sure it is securely inserted.
Make sure the USB device is of a mass
