The device itself is a continuing wow moment for me. But in regards to the FM transmitter it had a surprise easter egg. I drive a Prius, as such the control head is digital so I see all of the sub-band text information a station sends out. The system will also keep the station ID and put it into the "button" on the touch screen. I was very surprised the second time, I went to play music through my car radio. The button to which I set the open channel I use had the station label "NOKIA".
