By plane [edit]. The largest gateway for air travel is Frankfurt Main airport in central Germany, which offers connections to all continents and to most airports in Europe. Zurich, Munich, Vienna and Warsaw airports are a lot smaller but provide good connections to selected regional and intl. destinations.
To connect via Bluetooth, first turn on your phone or tablet's Bluetooth. When you use a new Bluetooth accessory, pair it with your phone or tablet. After pairing, devices can connect with each other automatically. Important: On a tablet that people share, each person can change the overall Bluetooth settings.
Bad news, the bluetooth phone features simply do not work. You can initiate a call form the Sync and the phone will dial and connect, but 5 seconds into the call the bluetooth disconnects the phone audio and returns you to your radio or whatever source you were listening to.) Re-pairing the iPhone 6 with Sync. Apparently the same phone name stored in Sync from the iPhone 5 was corrupting the settings for the iPhone 6 using the same device name. I hope this helps. Good luck!
