Personally I’m a huge fan of TomTom Go. It’s free to try out, but costs money if you want to use it for anything but a negligible amount.
TomTom has really dialed in the turn by turn directions over the years, and of all the navigation software I’ve tried over the years they still reign on top.
And in a country littered with speed cameras I’m more than happy to cough up $20 a year for a family subscription.
