I have a suzuki cultus 2020 AGS. The clarion entertainment unit that comes pre-installed has stopped working suddenly. It was working in the afternoon but when I switched on at night the unit isn't working. All the lights are working fine even when I press the disc eject button I can hear the nlusual whizzing sound but the display isn't working I have tried the power on/off button but nothing happens. Can anyone assist me on diagnosing what could be the issue? I don't want to take the car to an electrician yet.
