I have a D100 installed and coupled to an Av Map EK IV.
The other day set QNH and all else, all ok . the set off on 83nm trip to my sons property cruising at 5500ft and approx. 30mn into journey efis altimeter display went crasy.
Showed me flying at FL370.OAT & density alt also incorrect.
TAS was showing at 185 kts  (correct TAS 110kts)
Have downloaded the latest Version(yesterday) all other functions correct. Alt still incorrect shows -1200 when  on ground. Local elevation is 965 ft. Cannot get it to alter..
