Most common questions used to investigate
Is the player powering up?
Has the car been started or at least put into ignition mode?
Does the car have a flat battery or a battery with low power?
Has the player been connected with the power supply cables properly?
Has the power button been pressed according to the sequence specified by the manufacturer?
Check the fuse box. Is there any blown fuse present in the box?
Has the mode on the player been set to the connected/correct channel?
Is the player playing any sound?
Is the volume high enough?
Have the speakers been connected properly?
Is there extra noise coming from the speakers?
Is the player having trouble reading media from a removable storage device?
Common conclusions
The player will not have any power until the keys are turned towards ignition. This is a security measure that most cars have.
As the device requires electricity to power up, with a dead battery it is not receiving the power. Recharge the battery using an external jump starter kit or something else.
First take the console out of the main slot and connect the wires which are extending from the back. You can also hire a professional to do it.
Many consoles have a programmed logic for the power button that by pushing it for 3 seconds or pressing it continuously multiple times will turn it ON. Read the instruction manual and try again.
As the whole cars electronics is connected to a single power source, a fuse box has been used to stop the burning of the whole system. The fuse related to the console may be blown out due to a fault in the electronics or any sudden power surge. Replace it with a new one.
Most players have multiple modes such as radio, Bluetooth, aux etc. Change it accordingly and try again.
The problem may be with the player itself or the device being connected to it. It is best to first get it diagnosed by a professional.
Increase the volume to a certain value so the sound may be audible.
The speakers also have to be connected to the player using their own wires. Get them connected or check if the connections have been properly done.
The problem may be with the speakers being faulty ore the media being played having an incompatible format. It is best to first get it diagnosed by a professional.
Change the sound settings using the in-built equalizer and try again. Also check if there is any electronic/magnetic device placed close to the speakers that may be causing interference.
The storage device may be faulty or the content being played is not in a format which is readable by the player. Read the instruction manual and try again.
For any further problems, contact the original manufacturer or a local technician to get it diagnosed.
