Garmin, TomTom, Mitac consider adding mobile TV to nav units

While they'd hardly be treading new territory, DigiTmes is reporting that GPS bigwigs Garmin, TomTom, and Mitac are all considering adding mobile TV functionality to their navigation units, an area they've previously shied away from. According to DigiTimes, some unspecified manufacturers say that by simply using their devices for plain-old navigation, customers are "unable to fully utilize their PNDs," and that adding mobile TV would "bring about a new selling point." While that remains to be seen, at least some folks seem to be big on the idea , with "sources at chipmakers" describing the potentially-upgraded navigation units as a "key device for future mobile TV deployment."
