Good packed and arrived quickly the installation was in my Fiat Ducato a matter of 15 minutes. The radio has a good sound and playback of MP3 files via USB flash drive is working properly. During installation you must be sure to get the power supply with the correct polarity, otherwise all stored / programmed actions are after switching off via the ignition key off again. The control buttons are a bit small and therefore used to. Overall, a recommendable device.
