I was looking into some things and I believe that Freescale makes the chips used in all OEM infotainment systems for cars in North America. They're usually something from the i.MX series. This is what was in reporter Michael Hasting's Mercedes C250. I found it in my '16 Mazda - funny thing is, everyone is reporting antenna issues with the Mazdas: http://mazda3revolution.com/forums/2014-mazda-3-skyactiv-audio-electronics/34442-poor-radio-signal-antenna.html

These are the models that have come out since Hastings' '13 death. The most common solution to the weak antenna problems seems to be that the antennas are just not getting connected during assembly. They are either left unconnected to the "shark fin" on top, or they are left dangling free behind the dash when there is no fin (in which case the antenna is built into the rear glass). If this was missed on a few vehicles, ok, that's just a QC issue. When it spans multiple years and every model, that's more suspicious. They have also disabled the WiFi features of the infotainment system, which are still present on the chip, and which were active in previous models.

Makes me curious what, if anything, Mazda's engineers found on it. They don't make the infotainment system themselves, they buy it from a company called Johnson Controls.

What a coincidence.
