GRT Horizon 10.1 and Sport 10.1 software change history

• 10.1 2.01 (2022-10-26)
  • Fix possible failure to display Discovery version information

  • Fix flight plan select and user waypoint list overlapping with DELETE prompts
  • Move flight plan Delete function to button
  • Lower minimum valid airspeed for newer High Speed to 24 knots

• 10.1 2.00 (2022-07-27)
  • Use split plan pages when both RNG buttons pushed
  • Fix low resolution terrain display on map inset when Synthetic Vision terrain isn't available (Sport 10.1 without Synthetic Vision option)
  • Fix EFIS model name in Bluetooth name

  • Improve performance of Serial Port Combiner (SPC) input
  • Add Serial Port Combiner error counters to checksum status page
  • Update magnetic field model to IGRF13 2020-2025
  • Fix calibration comparison and sync of missing magnetometer serial number and add user override. Many magnetometers made before 2020 report their serial number as zero. This causes incorrect sync of calibration data between separate magnetometers. Magnetometer serial number zero is now ignored and requires an override to sync calibration data. The Mag Cal Data Sync menu now reports magnetometer serial numbers. If they are zero or otherwise incorrect, user can assign each magnetometer a number from 1-4 to match them up.
