Description
The Dakota Digital GRFX-55C Grafix Series instrument system is designed specifically for the 1955-56 Chevy Car, bringing fully customizable digital instrumentation to one of the most iconic cars of the Tri-Five era. The Grafix Series allows the user to personalize nearly every aspect of the display, including graphic themes, display colors, warning modes, and gauge styles.
Each gauge location can be configured as Analog, Digital, or Bar-graph style, and displays can show readings singly, grouped in pairs, or reconfigured entirely to show different information. The system also integrates reverse backup video display capability, onboard GPS for automatic speedometer calibration regardless of tire size or gearing, and built-in Bluetooth technology for wireless access to the Dakota Digital App for configuration, calibration, and real-time diagnostics.
An external control module is used to simplify wiring and keep installation clean, and the system includes a complete sensor package. An optional GLC-55C clock with a chromed machined aluminum bezel is available separately to complement the instrument cluster. All Dakota Digital instrument systems are engineered and produced in Sioux Falls, South Dakota, and are backed by a Limited Lifetime Warranty.
