We have a D100 that works well with my Garmin 296 and shows the course on the HSI but when we tried with a 495/6 the menu seems to be different and we could not get it to talk to the HSI it only seems to have 1 serial port where the 295 shows 2 of which we seem to be using port 2 How should we set the 495 menu to let it talk to the HSI
Thanks
