Bluetooth setup on the Kenwood is kind of PITA. From the main menu select Bluetooth, then setup. Then you should be able to tell your device to search and you should see DNX... and select pair. You should get a code on both your DNX and your phone, select pair and you should be done. It is all in the manual, but easier than what is decribed in the manual.
