...LaCrosse. Rental companies navigation? the m35, and the lacrosse have built in navi, but alamo and avis charge for navigation, but do their cars still have the original car's feature, if so, can we use the car's built in system with no charge?
Rental companies actually take the disc off the built in navigation for these cars (or at least somehow deactivate it); this way these rental car companies attach in their portable nav systems and charge you for it.
