Learning all over again. I also have the X52 and am slowly learning which buttons to reprogram.
I did start off by going to the mapping section in the map and if you select mode 2 (for GVs), then look to the top left and under default, there is an option to duplicate mode 1.
I started there so I at least had my VOX set up in GVs. Then I had to remap a VOX button to my joystick so I could keep my left hand free to drive and steer.
The noob feeling in a GV definately sux...
Trying to get it down so the noobs don't tear me up.
The only way I can really zoom in is in commander's position so I need to set up some toggles for quick scouting and recons.
And yes... ...I am killing the heck out of some grass too. Too bad we don't get perks for it!
Good luck!!! If I learn anything else new, I'll be sure to post it here.
