Just finished the whole installation over the weekend.  here are the thing done:

- painted the center console to black to match the interior more

- installed the Alpine blackbird navigation system with the screen.

- replaced the Pioneer AV unit to JVC AV unit.

- added under glow light to footrest area.

The blackbird navigation unit is installed inside the armrest storage and wired to the dedicated screen at the original cup holder space.  The screen is actually a touch screen so you can pretty much control everything from the it without touching the navigation unit.  for DVD entertainment, the JVC AV unit is hooked up to the additional screen as well, so both screen in front plays movie at the same time.
