One problem I do have, however, is the reflection off my tan leather during the daytime. When it's bright outside (everyday here in SD) and bounces off the tan leather, it makes the screen kinda hard to see.
Sometimes I just have to hold my hand over it for a moment. Even with tinted windows up.
This would not be a problem for someone with a darker interior.... even grey cloth would make a world of difference.
Also, the antenna wire does not bring the antenna down while listening to a CD or MP3. Pain in the ***, I like to bump my music in the car wash. I wired in a small radio shack switch for full manual control on the antenna.
