| they'll knock you if they think you were watching a movie or something on it while you were driving, and often it's the officer's discretion. A lot of people I hear get away with switching a movie or whatnot to a nav screen before the cop gets to their door. Navigation systems are fine, it's entertainment systems that they charge for. Like I said though, a lot of it is not written law as far as multi-use systems go, so often it is officer discretion. |
