AEM's X-Series GPS Speedometer (PN 30-0313) display ground speed, course and altitude via an included 10Hz GPS receiver. Users can integrate the X-Series GPS Speedo into an Infinity ECU to add track mapping, and an included Vehicle Speed signal can be outputted to an existing speedometer to eliminate the need for a vehicle speed sensor. A 10Hz GPS receiver receives speed, heading and altitude data from multiple satellites at 10 samples/second providing excellent accuracy and reliability. The GPS receiver includes a magnet and adhesive bottom for exterior mounting on the vehicle. The X-Series GPS Speedometer Gauge has a bright four-digit LED display that is 87% larger than our original digital gauges and provides better readability. A sweeping LED "needle" lines the edge of the gauge face for quick reference. A 33% overall increase in the gauge face display makes it easier to see at a glance. X-Series Gauges come with a black bezel and faceplate, and an optional silver bezel/white faceplate accessory kit is available (PN 30-0313-ACC, sold separately). Despite the larger display, X-Series Gauges are contained in a standard 2-1/16th-inch (52mm) diameter housing for mounting in a standard gauge pod. Thanks to an advanced single board design, X-Series Gauges have an incredibly slim overall depth of under 0.825", with a cup depth of only 0.200." This shallow cup depth allows X-Series Digital Gauges to be mounted practically anywhere.
