NU-CHY2
Chrysler/Dodge/Jeep
Navigation Unlock
Integration Interface
*These instructions only support revision 1.1.4 or higher of the NU-CHY1
Installation: Disconnect the main 22-pin harness from the back of the radio.
Plug the male connector on the NU-CHY2 harness into the 22-pin port on the
back of the radio. Connect the factory 22-pin harness into the female connector
on the NU-CHY2 harness.Plug the Black micro-t 24-pin connector on the NU-
CHY2 harness into the NU-CHY2.
In vehicles equipped with a Multi-Function Display (MFD) in the instrument
cluster or an external Uconnect module it is not necessary to connect and mount
the LED. The best way to determine if the UConnect is external is if the vehicle
has an external iPod or USB input (not including the one built into the front of the
radio). If the vehicle is not equipped with an MFD or external Uconnect module
mount the LED in a location that is visible to the driver.
If you wish to enable the reverse camera unlock feature you must power up the
factory reverse camera (this does not apply to the 2010+ Dodge Ram or 2011+
Jeep Grand Cherokee). To do this a wire must be ran from the NU-CHY2’s
red camera turn on wire to the factory power wire for the reverse camera. The
location of this wire will vary depending upon which vehicle you are installing the
NU-CHY2 into. Please see below for the different locations.
Please Note: If the customer does not wish to use the Reverse Camera unlock
feature you do not have to locate and connect this wire.
The NU-CHY2 is a Navigation Unlock integration interface that allows the factory navigation features of
your Chrysler/Dodge/Jeep radio or the reverse camera to be used by the passenger at anytime.

1. You will need to locate the reverse camera wire in the rear harness located
above the rear door trim panel (Fig A).
2. The reverse camera wire is the white/green wire (test with a DMM to verify
12v when the vehicle is shifted into reverse) (Fig- B).
3. Connect the red camera turn on wire from the NU-CHY2 to the white/green
wire using a diode (Fig C). The diode is needed to prevent the reverse lights
from coming on when the reverse camera is activated.
4. Verify that the reverse lights do not come on when the reverse camera
unlock feature is being used.
