Gotta check this out, its awesome!!

Google maps does this for me

 

It also has an interactive tool that will mark cops along the way and alert other waze users of speed traps, which are ILLEGAL in the state of CA mommie tunkie

 

WAZE is awesome. Its basically free turn by turn navigation!

 

with traffic data and police locations...

 

+1

 

this app use a lot of data, right?

 

no, it uses very little actually. You can ask the app to "compress data" further, you just get slower updates (i think?). I remember using it for a week and not going over 10-15 mb. Of course it depends on users in your area, how far you're traveling etc.

 

my favorite navigation.
tops all the paid apps and expensive portable units out there.

 

The one or two times I did use it I liked it. I need to get a modifry bracket and holder for my phone soon.
