Maximum disappointed by Sony :(

Before I ordered the Sony, I had the support of Sony written if I can use the MEX-N5100BT with my steering wheel remote control on. In response, I've got a YES and get a PDF with the user manual. In the stands, I can program the occupancy even free. An old shit !!! More about that later. Ordered and fast delivery, despite all holiday so I looked forward. The first disappointment came as the postman with a slightly damaged box came. With the messenger package and cardboard items unpacked thankfully okay despite packing without filler. So get into the car and off you go ...
- There is no antenna adapter included as with my old Radio (Sony CDX-GT 450U)
- There is no case to keep them for the panel
- The radio and having delivered harness has at no remote connection to or off a power amplifier
Actually, I was already operated genuine. Turned on the radio and worked primarily by the extremely overloaded menu.
- No function of the steering wheel remote control also tries to adjust the allocation of the Steering menu. Nothing since the occupation make as my old radio was not possible despite several attempts. Display the radio repeatedly Error.
- My USB Flash Drive (8GB Intenso mini) infected because I wanted to check the new Equalizer times and lo and behold the shit goes on. Display NO DEVICE.
According to BA, the radio recognizes the stick although not 30min before that ran in the old radio. I've formatted the drive and re-recorded no success. I still have 2 other sticks tried the same result NODEVICE or noaudio. I had my Vaio with the car and got but everything checked no success on the radio even a sound via USB to elicit.
- With the Bluetooth continues the shit, repeatedly, the display attempts to mate with Sony Xperia Z1 Compact no chance.
Only with my USB cable and the function AUTOPairing worked joining BT but it did not work, despite several attempts to use the phonebook to access.

I'm actually genuine Sony fan but I had the part processed preferably with nem hammer.

If everything would have worked if they were 5 star but not become so. Operation is really cumbersome and impractical. To play a CD or function from tuner, it is not even come.
