Troubleshooting
1. Errors which occur during the operation or installation of the
device may be mistaken as a malfunction of the actual device.
2. If you are having problems with the device, try the suggestions
listed below.
3. If the problems persist, contact your dealer.
Problem Possible Cause
There are small red,
blue, or green dots on
the screen
• Because the LCD is manufactured with
technology requiring high point density,
a pixel or lighting deficiency may occur
within 0.01% of total pixels
The sound or image is
not working
• Has the ignition for the vehicle been
turned to [ACC] or [ON]?
• Has the SYSTEM been turned OFF?
The screen is being
displayed but sound is
not working
• Has the volume been set to a low level?
• Has the volume been muted?
When the power is
turned on, the corners
of the screen are dark
• The display appearing somewhat dark
after prolonged periods of use is normal
with LCD panels. It is not a malfunction
• If the screen is very dark, contact your
nearest dealer for assistance
Sound is working from
only one speaker
• Are the positions of Fader or Balance
sound controls adjusted to only one
side?
Problem Possible Cause
Sound does not work in
AUX mode
• Are the audio connector jacks fully
inserted into the AUX sockets?
The external device is
not working
• Is the external device connected with a
standard connector cable?
Upon turning power on,
the most recent mode
screen is not displayed
Within modes that play files by reading
external sources, such as USB, iPod,
or Bluetooth streaming mode, the most
recently played mode screen prior to turn-
ing off power may not properly load.
• If the corresponding device is not con-
nected, the mode operated prior to the
most recent mode will operate
• If the previous mode still cannot be
properly played, the mode operated
prior to that will operate
