Description
The Dakota Digital GRFX-57C is a revolutionary Grafix Series instrument system engineered to fit directly into the stock bezels of a 1957 Chevy car, bringing a fully modern, customizable gauge display to one of the most iconic cars ever produced. Nearly every aspect of the display can be personalized, with multiple graphic themes, user-selectable colors, and warning modes, while each gauge location can be configured as Analog, Digital, or Bar-graph style, shown singly, paired for twice the visible data, or reconfigured entirely.
The GRFX-57C integrates a reverse backup video display directly within the instrument cluster using its largest onboard display, with compatible backup cameras available separately. Onboard GPS technology enables automatic, no-touch speedometer calibration regardless of tire size or gearing, while a wired VSS source provides a real-time speed signal. Built-in Bluetooth connects to the Dakota Digital App for configuration, calibration, and real-time diagnostics, and a USB port allows for future field updates and new graphic theme imports. An integrated G-force meter displays real-time driving dynamics for cornering, launching, and braking.
As with all Dakota Digital systems, the GRFX-57C utilizes an external control module to simplify wiring and keep the installation clean. A matching GLC-57C clock is available separately for the passenger side. Completely engineered and produced in Sioux Falls, South Dakota, this system carries a Limited Lifetime Warranty.
