Garmin RV14 not fully functioning

[18889]

My GTN750 does not seem to allow me to activate legs nor does it allow vectors to final either, is this normal? Whatever airfield I go to if i position downwind and select approach, the vector to final is blurred out, and even when i steer myself onto a base leg and try to activate a leg, that too is not selectable? I can put the whole procedure in from miles away but thats it. 

I am fully updated with the latest Garmin and TDS updates.

Any help appreciated as its not behaving as it should.

Cheers Stu
