as a canadian prius c owner, the infotainment system is *ahem* not that great. there is zero traffic info and the mapping application will never get updated. consequently i often have my phone running google maps turn-by-turn through bluetooth when i need directions. i'm considering a car mount, and was curious if anyone else has done a similar setup on their c. is there a particular option that works well for the c's dash layout? i'm leaning towards one of the ones that clips onto a vent rather than some sort of suction thing, but i'm open to whatever works best. i'm also wanting to make sure there's no issues with people getting pulled over for having their phones running (even if its just replacing the car's gps functionality). thanks for any advice!
