How to make the sound come
out through the speakers in
the car
1. The built-in speaker of our device can emit sound, you can turn it
off in the system settings
2. Transmit the sound to the original car radio through the FM
transmitting function of the device (for example: select 86.3MHZ
on the device, and then play USB music, then use the car radio to
search for 86.3MHZ);
3. Transmit the audio to the original car player through the AUX
OUT (3.5MM) interface of the machine (only some models have
this interface).
Bluetooth not working properly Delete the paired “SWL-BT” on the mobile phone, and then re-
search the Bluetooth name
“SWL-BT”. After the pairing is successful, it can be used normally.
Can’t automatically connect with
CarPlay or Android Auto
1. You need to set CarPlay or Android Auto as the default
connection mode on the Phonelink setting interface.

mobile phone, and then when the Bluetooth is connected, it will
automatically jump to the CarPlay or Android Auto interface.
