BMW offers in-car navigation throughout its range. In August 2000, its mapping extended beyond Melbourne and Sydney to include all mainland capital cities and the major highways linking them. The recent upgrade included the ability to nominate destinations by street number. The Philips CARIN-based system was introduced in October, 1998, and operates via the BMW On Board Monitor fitted standard to many models and optional on most others. Voice control is now offered as an option on all BMW 7 Series models, all of which feature sat-nav as standard.
