Main supply  
(red) wire:  
The main supply wire must be 
connected to a main supply 
terminal. To do so, locate a 
main supply terminal/wire 
with a constant +12 V power 
supply. These are available  
at the:
• car battery
• fuse box
• car sound system
If the radio does not support the mute feature, use a relay to provide the 
feature (with the customer’s consent). Read the car sound system manual 
before touching any wires behind the unit.
Some vehicles do not come equipped with an IGNS connection. This 
connection is not necessary for operation of the Nokia Display Car Kit 
CK-600. The blue wire can be left unconnected.
