The only downside I have is the direct sunlight viewing wash out. But other then that I love it.
It could use to have better sound processing abilities (EQ / time delay). But that would only increase costs and most people don't need or want that kind of control.
I have been talking to a buddy with a V-ride and I really want to try to modify his dash to do the same. I thought of trying to find a quad gauge like the one my boat uses to get rid of the three little gauges then build a fiberglass pod to get his speed control multi line box to the side or swap his boat to perfect pass and ditch the stock speedo for it.
But he is not quite as adventurous as me,
