OnStar has slotted the last piece into its Connected by OnStar 4G LTE service today by finally laying out its price plans for in-car data. The LTE data service will see a radio and WiFi access point installed in the 2015 Chevy Malibu and to some 30 other GM cars by year end. Both US and Canadian packages have been announced with tiers for monthly users, plus day and year passes for more flexible usage. Unfortunately, the curated app store we've heard about won't see the light of day in 2015. So, while it's great to have simplified data access and improved service with simultaneous data and voice, the delay may temper your enthusiasm.
