Remember Mavizon's plans for its Mavia car tracking device (formerly the AutoBot) from almost two years ago? The company promised availability sometime in 2012, and we're here in earnest with the car companion ready for pre-order. The business model has changed significantly since 2010, however. It's a cheaper $169 up front for the Bluetooth cellular OBD-II peripheral -- $99 for the first hundred through the gates, or $299 for a two-pack -- but the full tracking service will cost $5 a month, or $49 every year. Those who do make the leap can get a look at their car's vital signs as well as set up geofenced notifications, track long-term performance and receive impromptu driving directions to a friend's coffee shop check-in. The first batch of Mavia units should arrive within several weeks, we're told, and should have both browser- as well as iPhone-based apps waiting in the wings.
