This is a simple tweak that enables Turn-By-Turn navigation (Apple Maps) on all countries (even those not supported, like Brazil). Just install and respring. No options.
Works on iOS 6 & 7. No options to configure.
Unfortunately, Apple doesn't have turn-by-turn directions available for all countries. Give it a try and let us know if it works in your country!
MapsAllCountries can be installed from the BigBoss Cydia Repository.
