The Sport uses this data to drive its graphical engine display and compute additional engine performance information. The EIS is available with or without a display.
Page 22: Gps Receiver Compatibility
September 2019 GPS Receiver Compatibility The Sport/Horizon 10.1 is intended to be used with an external GPS receiver. The EFIS supports two inputs for redundancy. The external GPS can be a remote unit (no display), or a stand-alone GPS navigator that does allow the pilot to enter a flight plan. Practially all GPS receivers provide a serial output that is compatible with the EFIS.
