I would like to share my own experience. I have just bought the very new BMW Car Hotspot LTE. It is very expensive supposed to bring the 4G capability into the car. It works very well in my car (2012 F20 125i with nav pro 609 and bluetooth 6NL). However, I was very very desappointed to see that this car Hotspot has no bluetooth capability (no chip) and consequently no rSAP. It means that I will never be able to use the embedded antenna with my Samsung Galaxy Note 2 .
