Installation in my Hyundai Coupe went jiffy, the connections fit straight away. The configuration also went jiffy because the settings have to be quite intuitive after a brief look at the manual (as 54-year-old, I sometimes do myself a bit heavy with something like that, especially at my previous Radio Pioneer DEH P88RS has almost fingers broken when times would adjust what and außerden you always forget how it actually went). When Sony: better sound, rich bass without a subwoofer, bass boost at low volumes ("Loudness") works really really well. Six pre-selectable equalizer presets ("XPLOD" sounds to my ears with music on most saturated). Other equalizer setting can be individually programmed. So, sound and reception quality leave nothing to be desired, and I can not understand why I had bought a 600-Euro-Radio me 5 years ago.
The Bluetooth connection to my mobile phone Motorola Razr V3, built in 2005, works after a single pairing problems. After deactivating a single press of the button on the BT radio is enough to to the last connected mobile phone to reconnect (provided you have Bluetooth on mobile phone at all on). The car's speakers can be reliably switched to mobile phone, assuming phone conversations or selects. The theoretical assumption of address books entries I did not try, I therefore can not vote.
Play MP3 files from the flash drive is perfect, however, may not stand on the stick in subdirectories, but in the main directory.
The only strange peculiarity: After turning off the ignition, the radio says: tüttt, tüttt, tüttt, tüttt. But that should be able to live. So, for all skeptics: strong buy recommendation. It`sa Sony!
