Interesting idea.

The "Bluetooth Pairing" message seems to be a ULF thing, as does the eject box.

If no paired mobile phone is detected inside the vehicle, the message “PHONE CONNECTED?” or “ACTIVATE PHONE” appears on the display or monitor

I am certainly left with the "ACTIVATE PHONE" at the end of the 2 mins of "Searching...".

I get the feeling that these are locked into a 1:1 pairing with a car installed phone and need to be in some way coded to be free to Pair with any phone, not just a dealer supplied, and car installed one. Or I could have it completely wrong
