2014-2017 Chevrolet / GMC Vehicles

Introduction & Features

The VS41 in an intelligent 4 camera switcher for controlling front, rear, and blind spot cameras. It is designed to be
used with PAC radio replacement interfaces.

Important Notes

1. These instructions are specically for adding reverse, blind spot, and front cameras (or any combination of the three) to an

aftermarket radio in the following vehicles:

• 2014-2017 Chevrolet Silverado, Suburban, or Tahoe

• 2014-2017 GMC Sierra, or Yukon

2. The VS41 video output will always default to the signal from Input 1 when none of the input triggers are activated. This

Input is ideal for connecting the rear (reverse) camera.

3. The VS41 inputs have priority in descending numerical order. For example: If you have Input 3 or 4 triggered, then you
trigger a lower number input (for example Input 2), Input 2 will take priority over the higher numbered Input.

4. The input triggers can accept either a pulsed or constant input, making them ideal for connecting to a turn signal as a
trigger.

5. The reverse trigger output will provide a 150 mA 12v (+) trigger while any of the input triggers are activated.

6. Upon deactivation of the last positive or negative trigger, the last video input source and the reverse trigger output will

remain active for an additional 3 seconds. (Not applicable when used with a BCI-, RP4.2-, or RP5.2- interface).

7. If there is poor video quality after installation of this module, please ensure quality connections on any RCA connections.

8. The positive input triggers accept input voltages in the range of 2v to 12v.
