I just bought a 2006 JGC Laredo without navi and without the boston acoustic speakers. Right now it doesnt have the steering wheel radio controls, any idea if my stereo has the plug in that back? If it does, where can i get the switches and wires?

Anyone ever do this? Is it very involved?

Thanks

your radio will have the ability to use them and the switches can be bought from the dealer.


OPERATION
The six switches in the two remote radio switch units are normally open, resistor multiplexed momentary switches

that are hard wired to the Instrument cluster through the clockspring. The instrument cluster sends a five volt reference
signal to both switch units on one circuit, and senses the status of all of the switches by reading the voltage
drop on a second circuit.
When the instrument cluster senses an input (voltage drop) from any one of the remote radio switches, it sends the
proper switch status messages on the Controller Area Network (CAN) data bus to the radio. The electronic circuitry
within the radio is programmed to respond to these remote radio switch status messages by adjusting the radio

settings as requested.

REMOVAL
WARNING: DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, SEAT BELT TENSIONER, SIDE AIRBAG, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES
FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS
OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE
THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
