Unit unpacked magnetic base Mini Star bolted 27 - plug in the 12V power supply and switched on.
Nothing except noise. By car the location widely changed-nothing. 1 time I had a bit of luck - I had 2 wireless operator in speakers, but still poor reception.
As I read the recessions ever before, I thought with the devices I can not go wrong. Unfortunately, far from it. So when buying new you prefer let advised by the dealer.
Device still looks good and there are plenty of small items for installation in the vehicle.
