Hmm, the picture is not visible. But....
I found a vehicle tracking device under the dash of my 2017 FFE. A bit unsettling, but I believe it was a fleet tracking device, not specific to the individual driver, me. I removed it, and tossed it into the garbage. I tried to find out who had contracted its use, but the manufacturer's website was quite useless, and I did not feel in the mood to do some social engineering.
Thanks for fixing the link to the photo. Nope, mine was up under the dash, and was a larger,flatter package. Yours might be a tracker as well, but it seems to be intentionally mounting in a readily accessible area. Maybe it is an interface? Like those old ignition immobilizers of the 70's and 80's? You had to stick a little circuit board "key" into a connector to enable ignition.
If I did not know better, I might think it was an OBDII extension. Just remove the cap and plug in. But since I can't be there to see if that is really a cap or not. Who knows what it is for?
