Pac-Audio GM1A-RST Radio Replacement Interface Module for Select 2000-2013 Buick, Chevrolet, Cadillac, GMC, Hummer, Isuzu, Oldsmobile, Pontiac, Sabb or Saturn Vehicles
The GM1A-RST interface allows the replacement of a factory radio in select General Motors vehicles with the Class II Data-Bus. Using this interface will retain factory features such as Warning Chimes, Bose Amplifier, Steering Wheel Controls (SWC), Rear Seat Entertainment (RSE), and Rear Seat Controls (RSC) when the original radio is removed.
The GM1A-RST provides data bus driven outputs such as retained accessory power (RAP), vehicle speed signal (VSS), illumination, reverse trigger and parking brake. You can also add multiple camera inputs to your aftermarket radio with Data-Bus controlled automatic activation (front camera only) by connecting a VS41 into the expansion port on the GM1A-RST.
Important Notes
- The included chime speaker should only be used if you are connecting an aftermarket amplifier to the cabin speakers.
- Aftermarket radio must have an auxiliary input in order to retain RSE audio.
- In vehicles with Premium Bose (Y91 / UQA) the chime volume can only be adjusted on the module via the adjustment dial. Please refer to page 3 under adjustable settings for further details.
- Aftermarket radios with a 2-wire resistive based SWC circuit (Key 1 / Key 2 wires) will not have default button assignments programmed. Please refer to the owners manual of the radio you are installing to find out the proper SWC programming procedure.
- When using real time speaker fading (Premium Bose only), if the fader setting is biased more to the front or rear, as the radio turns on the sound may begin at the default setting and then quickly transition to your custom setting.
- Aftermarket radio features such as High Pass Filters (crossovers), DSP or “Network Mode” will interfere with proper fader function (Premium Bose only). In order for the GM1A-RST’s fader function to work, the audio from the aftermarket radio’s output must match so it can compare the front and rear audio levels and determine the proper fader setting for the factory amplifier.
- When used in conjunction with the add on camera controller (VS41) the GM1A-RST will only provide Data-Bus controlled automatic activation for the front camera. Please refer to the vehicle specific VS41 instructions for more detail.
