Just found out that the new Garmin G500 TXi PFD/MFD/EIS with on screen engine monitor I heard rumored about 2 years that I have been anxiously waiting for ago has FINALLY come out this month as of 10/4/2017, and looks GREAT! Ready to pull the trigger when available. Hoping that their engine monitoring system is certified as primary as that would solve many panel space problems. I think I need one!
