NAVRGB does not replace or add a factory navigation system, it only creates additional video inputs for the navigation system or color screen. NAVRGB video interface is 100% PLUG & PLAY - no wire cutting required. NavTool PLUG & PLAY installation harnesses are made using OEM connectors. NAVRGB video interfaces come with two composite video inputs: video 1 is dedicated for any video source, video 2 is dedicated for back-up camera. When the vehicle is in reverse, the screen will automatically switch to reverse camera (back-up camera overrides both DVD and navigation screen). NAVRGB is an externally wired Plug & Play video interface that is installed in-line of the navigation computer and navigation screen. It works simply by interrupting the video signal from the navigation computer when it is activated, or when 12V are applied on the reverse camera line. When this occurs the navigation system video image will be replaced by the video source that is connected to the NavTool interface. NAVRGB is a video-only input interface module and does not have any audio inputs. If the vehicle does not have a factory-installed AUX audio jack, then an audio FM modulator/transmitter or an auxiliary audio input interface adapter is needed to connect audio signals from an external AV source to the factory audio system. NavTool is video-in-motion enabled, so the video image will stay on the screen even with the car in motion, however we do not recommend doing this. The factory navigation computer cannot play DVD movies, a video source is needed to display video on the factory navigation screen. Examples of video sources: DVD player, Game Console, Digital Media Player, iPod Video (NAVRGB does not support iPod Controls or iPod audio). $350.00 Other Parts for your 2004 SIERRA GMC Part # Description Photo Price Buy it now songm-11 OnStar Radio Replacement for Select GM Class II Vehicles The CRUX SONGM-11 is designed to allow for the installation of after-market radios while retaining OnStar functionality with Bose Amplified & Non-Amplified Systems, while also retaining Chime & Accessory features in a wide range of General Motors Class II Data-bus vehicles.
