Disconnect the black 14-pin and brown 16-pin harness from the back of the

radio. Connect the male 14 & 16 Pin connectors of the BCI-GM31 harness into

the 14-pin and 16-pin ports on the back of the radio. Connect the factory 14-pin

and 16-pin harness into the female connectors on the BCI-GM31 harness.

Connect the black 24-pin micro-t connector of the BCI-GM31 harness into the

BCI-GM31.

If you are adding a reverse camera:

The radio’s camera reverse input will need to be enabled via the dealership

using the GM MDI tool. Once enabled, disconnect the yellow RCA’s in the BCI-

GM31 harness and connect the radio side RCA to the aftermarket cameras

video output RCA. If you wish to be able to view the reverse camera at anytime

you must power up the aftermarket reverse camera via accessory +12V, not a

reverse +12v signal.

Vehicles equipped with a Factory Reverse Camera:

If you wish to enable the viewing of the reverse camera at anytime you must

power up the factory reverse camera when this feature is active. To do this a

wire must be ran from the BCI-GM31’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 BCI-GM31 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 BCI-GM31 is a Navigation Unlock integration interface that allows the factory navigation features

of your 29-bit GM LAN radio or the reverse camera to be used by the passenger at anytime.
