Yep, the Taurus would pick up cell calls and texts if he was connected to his bluetooth. And possibly the route if it has nav. Mercedes probably has more featuresCP story on Yahoo regarding the Nova Scotia shooter.
Police obtained data from infotainment systems in a 2013 Ford Taurus and 2015 MB C-300.
"Police say these systems can store synchronized cellphone data regarding navigation,texting,phone calls and internet-enabled content including traffic conditions and weather".
I would bet this can be accessed wirelessly with the right tools.
