My phone has been working just fine. I like not having to carry a bulky FOB in my pocket. Although I guess this is a good addition for those that have issues with their phones.

I assume this thing just has a built in BT transmitter that works like the phone. The car doesn't seem to have the hardware needed for a more traditional RF based keyless entry system.

The old fob is Bluetooth LE as well. Once folks get the new unit in hand we will be able to see what the differences are.
