Well guys it's raining so a nice evening to "revert". After about 20 flights I am convinced I've tried just about everything to get GPS hold to work as it did. I reverted to .90 (as I was running .88) Plugged the USB into the Nav board, and checked connection =ok Downloaded and updated to .90j: Got Error code 1 (FC not compatible) Downloaded the prior Nav update = .30h No Error = BUT got "MKTools not compatible" when I pushed the "settings" button. Please update to latest....well I have the latest? v2.00b Downloaded MKTools 1.80b into a separate folder =success! = "reverted" Comedy of errors!!!! lol A bit of a PIA but I got it done. Now I need to update all my settings (I have jpgs of all screens) And wait for the rain to stop!
