Magellan, Mio and Navman Switch to Tele Atlas

GPS Tracklog reports that GPS receivers from Magellan, Mio and Navman — all owned by MiTAC — are switching from Navteq to Tele Atlas as their map provider. Since TomTom owns Tele Atlas, does that mean that Garmin is the only major manufacturer of car-based GPS navigation devices that still uses Navteq?
