Ya the touch screen is not the easy to use when bouncing down the road. I think the touch screen is more of a cool factor then useful. Or cousre I don't have a sunlight readable one so its almsot uselsess during the day. I have steering wheel controls but just VOl up/down track up/down, mode and mute. I could use the basic functions with that but I need a little more too.
Glad to here your take Turbo on the space navigator. We really do need to steal ideas from OEM, because they spend tons of money of R&D to find the safest and most ergonimc ways to interface the radio. Will your thing you are working on look like Zorros CCstick?
I would almsot need something super flat like ribbon cable, the kind on thin plastic sheets. Is that what you meant by the LVDS cable? The wires from the parallel cable were pretty damn small, and I still didn't have room for those. I took a dremel to one button to make room, but I decided against that for now.
When I have a whoel day, my buddy and I are going to rip it apart again and hopefully figure out a way to get wires to each button. Maybe I just need bigger tactile buttons to allow me some space to fit wires. I dunno.
