HONDA 2010 Ridgeline - Manual (Page 210)

Your vehicle’s audio system will
disable itself if it is disconnected
from electrical power for any reason.
To make it work again, you must
enter a specific code with the preset
bars. Because there are hundreds of
number combinations possible from
the five digits, making the system
work without knowing the exact
code is nearly impossible.
If you lose the card, you must obtain
the code number from your dealer.
To do this, you will need the audio
system’s serial number.
You should have received a radio
code card that lists your audio
system’s code and serial numbers. It
is best to store this card in a safe
place at home. In addition, you
should write the audio system’s
serial number in this owner’s manual.
If your vehicle’s battery is
disconnected or goes dead, or the
radio fuse is removed, the audio
system will disable itself. If this
happens, you will see
‘‘ENTER CODE’’ in the frequency
display the next time you turn on the
system. Use the preset bars to enter
the code. The code is located on the
radio code card included in your
owner’s manual kit. When it is
entered correctly, the radio will start
playing. If you make a mistake entering the
code, do not start over; complete the
sequence, then enter the correct
code. You have ten tries to enter the
correct code. If you are unsuccessful
in ten attempts, you must then leave
the system on for 1 hour before
trying again.
