After reading your wonderful posts and doing some resarch, I got a Riocar yesterday and had it istalled in my 2002 Boxster. I'm getting the engine noise (the whine) through the sound system. Anyone had experience with this? Also, the illumination is not dimming with the rest of the interior lights. And, are the "buttons" supposed to be lighted? Finally, what color face plate is best...The amber is a bit off.

Many thanks!!!
