AP74 does not work in Nav mode

[innovair]

the AP 74 connected to the D180 which is also connected to GPS AVMAP EKPIV does not work in NAV mode under the function GOTO of the GPS whereas the DYNON display correctly the route in the HSI mode, any solution?

Are you seeing correct course, CDI, and ground track indication on the HSI display? If course is always pointing to 360, you'll first need to fix that by getting the latest AvMap firmware and setting the NMEA output to "processed". If you could take and post a picture of your Dynon HSI screen here, that would help us see what you're seeing too.
