My not-so-humble opinion :): Only owners of the devices should set button mappings. Never use the sim for it since it tells you nothing about what makes sense. I get the feeling that's what's gone on for x5.
agree 100% now, the #4 option that will be used is UP/DOWN selects items LEFT exits no change RIGHT applies and exits NAVI (a.k.a. select) makes change but does not exit dir OFF exits, cancels any changes
