Like some of the other people have posted, I have a Pioneer Double Din and it sucks for daytime driving. The sun washes out the screen to the point that is dangerous for me to focus on it to read it. Unacceptable.
So now I'm going to ditch my X5500 and am looking into more options. I can't seem to find anyone complaining about the 2013 Kenwood Double Dins, but I thought I'd ask here because it appears that the Tacoma's do an equally poor job of protecting the HU from the sun that my Camry does.
