My Trutrak Gemini screen will randomly turn grey with the AI display completely disappearing. If it was engaged and following a gps route it continues to control my aircraft as per normal. Also will continue controlling the craft if it is in track mode. If I cycle the power to it, it will come back to life. It did not do this trick in the beginning but just started this phenomenon after about 5 or 6 hours of operation. It then stopped doing it for awhile and now has started doing it once again. Anyone else have this issue?
