Only three stars.
For on road navigation, this app gets you there. With onboard maps, Worth the $10 for voice navigation. Functions fine in Cellular dead zones, as long as your GPS is up and running.
Off road navigation, forget about it, the app even has problems with parking lots.
iOS users with voice navigation: You can stop Copilot from screaming at you through SETTINGS / MUSIC / EQ select: Late Night.
