If your radio isn’t on the setting you’d like, continue to press the SRC/OFF button until you reach the source you’re looking for (like Bluetooth, FM radio, AM radio, USB, etc.). If you find that you’ve accidentally left the main menu, simply press and hold the BAND button with the arrow on it to return to the main menu.
To turn the radio on with the remote, hit the SRC button once. You can also use the SRC button to find the source you’d like, just like you would use the SRC/OFF button on the dashboard.
