Since radio is great, did not know that my old Astra Cabrio can so deliver great sound. The Bluetooth function is super easy and has a secure and stable connection. The device detects all mobile phones, with a brief acknowledgment everything is connected. The phonebook from the mobile phone is transmitted on the radio with all contacts in just a few seconds. everything is ready for use and make calls that's super easy, the dial can be scrolled and selected. The hearing and speech quality is great, even in an open convertible hears everything and is super well understood. tested at 80 km / h
