GRTAvionics recommends the MiniX Flight Director be updated every 56 days. Today was my first update ever. The AHRS software version 51 was updated to 58. The EFIS 1g (4-22-14) was updated to 2a (11-9-15). Air data was updated to version 10. I had remove the MiniX from the panel to get to the mini-sub connection located on the backside. I plan to fins a 6" extension that can be permanently mounted for easy access.
