thanks for the feedback still having trouble mapping 
I always thought the keyboard was default?
The keyboard is the default setup for most commands. Also default is the switch to "mode 2" when jumping into a GV I think. In the picture below, the top drop down box has "Saitek X45 flight control stick" yours should have what ever stick you are using or "mouse" if you have no stick. The drop down box BELOW that one is the one you need to check. It is labeled "Mode Selection" "Mode 1 (planes and Default)" and below that the "auto select mode at start"

Click the arrow and the drop down will open, select "Mode 2 (Vehicle and boats)". This will show you what is mapped to the keyboard in mode 2. If auto select mode is checked , when you jump into a GV this is the mappings that will be used. Be sure the commands you are trying to use are mapped out in this mode or they will not work.
