Required to be removable and can't be used at night. So standard window tint as we think of it is still against the vehicle code.
Cell phone has to be hands-free, but court rulings have said it's the act of talking on the phone with it in your hand that's illegal (because of how the law is written). So you can legally change your music or check your GPS as long as it doesn't get into wanton disregard for the safety of others.
They said that about a specific code that a specific cop wrote.
There is a second code that says using the phone for any kind of data usage is illegal.
The cop in the case law you are citing wrote the "talking" vehicle code for someone who was using the data portion of the phone.
So, no, you can't text and drive or edit your GPS and drive or check your e-mail and drive or MMS and drive or read BARF and drive. A cop also can't cite you for the talking-section of the vehicle code and have it stick in court. I think dialing, and perhaps as you said even adjusting your music is fine.
