PAC GM1A-RT RadioPRO Advanced Interface for General Motors Vehicles Instructions
VS41
Vehicle Specific Instructions for use with RadioPRO ADVANCED
In Select 2003-2006 Chevrolet / GMC Trucks and SUVs
Introduction & Features
The VS41 is 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 specifically for adding reverse, blind spot, and front cameras (or any combination of the three) to an
aftermarket radio in the following vehicles:
• 2003-2006 GM Trucks / SUVs
2. You must locate and connect to the analog turn signal wires in the vehicle, as well as connect the reverse output trigger
from the GM1A to the VS41. Please wire the VS41’s analog input triggers 1, 3 and 4 according to the instructions below.
3. Analog input trigger 2 on the VS41 only needs to be connected if you want manual activation of the front camera via toggle
switch. Automatic activation of the front camera (Input 2) via Class II Data-Bus commands can be set using the RadioPRO
PC application. See page 2 for more details on the RadioPRO PC app.
4. The reverse trigger output will provide a 150 mA 12v (+) trigger while any of the input triggers are activated.
5. 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.
6. 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.
7. If there is poor video quality after installation of this module, please ensure quality connections on all RCA connections.
