Garmin 430
Can anyone help me with the Garmin 430? I have had a play with the basic 'sim' which they produce, but I cannot seem to define my own waypoint by lat and long.
I can name a waypoint, say 51N1W. It then says 'create new waypoint?'
The problem is there is no prompt to input a lat/long and If I press 'ENT' it creates the waypoint where the 'sim' is, in this case at Cranfield. I did once have 'Modify?' displayed and thought I had cracked it, but nothing I then did gave me a lat/long prompt.
It is just possible the 'sim' has limited functionality, so I will try on a real aircraft, but the battery flattens very fast on the ground and I probably have better things to do in flight.
Failing everything, we will put groundpower on a a plane on maintenance in a couple of weeks, but I am quite keen to find out before that. Any Garmin 430 experts out there?
