+ Front USB slot, I have my iPhone 5 connected, which hangs on a bracket on the windshield. The iPhone is loaded and the announcements of Navis (Google / Apple Maps or Navigation App) can be heard through the car speakers.
+ Coupling via Bluetooth (dongle to rear USB) works without problems. I can call by radio the recently called contacts, select Contacts etc, start calls and hang up. Included micro fulfilled his ministry.
+ Listening to music via iPhone goes without problems (especially Spotify). Songs indexing etc goes on the radio.
+ The backlight and font color of the radio can be adjusted. I took the red color that is almost identical to the remaining Audi features.
+ Radio I hardly use - have stored some stations and RDS goes.
I am fully satisfied and would buy it again at any time.
