There's a hard volume up/down
There's a hard volume up/down on the steering wheel. No need for another button.
What they do lack is a PAUSE MUSIC button on the steering wheel. When the dash is showing music info the "enter" button really ought to be "pause". It currently does NOTHING in that mode!
The drive modes could be reconfigured through the head unit. The rev-matching feature is.
The screen is high res enough. But I want a faster processor and memory for my custom apps (rooted head unit allows this).
