Module functions

The module allows to access full information displayed by the display when there is no stock radio/EHU unit installed. Normally when no radio is installed, only Opel startup logo is shown and nothing more. This module acivates the display and gives an access to all of this functions.

It allows also to control the display by using two BC buttons used by MID display. It allows also to close the errors messages (like lights failure).

Additionally it allows you to connect the reverse camera to the display (additional video signal converter is required - it is not a part of this module).

  System information

Module installation

The uses 8 wires to connect to the car which must be correctly connected. Most of the signals can be found in the display connector (32 pins) and in BC knob connector (3 pins). There is no exact manual for each car because it may differ depending on car model. If you need any help with connecting - let me know (contact me).

+12V/IGN

module power (+12V). The best option is to cennect this signal to ignition or to accessory signal (key position I).

of course module will work fine when connected to direct +12V from the battery but it will consume unnecessary power when not used.

power usage is really low but is is not requried.

GND

module/battery ground

CAN_H

communication between the module and the display - CAN+

CAN_L

communication between the module and the display - CAN-

GND

module/battery ground - used by two control buttons (key1 & key2) - same signal for both keys. It is the same GND as the previously explained GND (connected internally in the module)

KEY_1

signal from the first key. Both keys are activated by shorting to the ground (GND)

KEY_2

signal from the second key

CAM

reverse camera enable signal. Reverse camera screen will be visible as long as +12V is applied to this pin.

When +12V voltage dissapears - camera view will be hidden.

The best option is to connect this pin to reverse light bulb voltage.

Module usage

Because the stock radio/EHU unit has a lot of buttons to use the display menu and here there are only two buttons available, to use this module you need to press the keys for a specified period of time. Times was arbitrally choosen for the best comfort of use it. After some tries if will be quite easy to use it. Following table explains fucntions of each buttons depennding on holding time.
