[Tiller control vs rudder control]

I know in the 737 rudder is also controlling the nose gear, but just with a very small angle, i think it was around 7 degreese, it would be nice if someone who have flown the aircraft could clarify how it is in real life with the A300

[Trim and Nav2]

Dear all, i have 2 questions?

1.) Is there any display to see the actual trim value?

2.) When using vatsim, i would like to use the nav2 aswell, is it working or deactivated?
