I also have my headlights on the whole time. I use the little wheel to adjust the brightness of the clock and illumination. My pioneer screen is set up separately based on time of day.
Maybe this will serve as the motivating factor to get it caged: you know you want to see this when you look over your shoulder at the evo you just passed
Ps. this isn't a new photo from the bc5..... we haven't touched it in ages
Where are you installing it? Are you putting it in place of the factory stereo? It might block your hazard light switch
Edit: to me it looks like it would fit with no issues
Unless you end up with a faulty GPS unit like me.....
Please make sure you log on regularly to check the GPS tracking is functioning as it should... I found out the hard way
