I think I use the Technology option (basically a big ring with a compass on the outside and selected info in middle). It pushes the gas gauge into top right corner (but still nice and legible). I think engine temp in top left as well (though it might be oil pressure).
Standard is OK, but I don't feel the need to see battery or oil pressure (or temp). My driving conditions are pretty mild.
What I DISLIKE about all of the options, is that none seem to have the odometer unless you're on the screen that provides that specific info. Since I don't trust the car's Nav I sometimes will use printed directions and like to know distance traveled from last turn/exit/etc. I haven't found a way to have odometer displayed and also be able to control radio functions from wheel.
Anybody have a solution to my odometer/radio coexistence?
Any chance GMC could revise or upgrade the cluster to add an odometer? Seems like pretty basic information one would want to have...
