Vinli wants to make any car built after 1996 “smart” with a plug that attaches to the car’s OBD port, giving the vehicle a Wi-Fi hot spot and access to applications on the user’s smartphone. Samsung Venture Investment Group and Cox Automotive are behind the $6.5 million in Series A funding for the company, which plans to launch the device this year with 20 apps, with an additional 120 in the works.
