I chose this rather simple model to equip my Scénic who had his poor cassette 2000. Finally I can listen to my CDs. I like this model for its simplicity, it is very intuitive and I dropped the user manual. I do not have the use of sound adjustements details but for people like me there are ready adjustments that make a good effect. The call system via bluetooth is super efficient and the connection between the devices is done in no time. I love the color settings configurable with several colors by zones. It's pretty fun. The facade is obviously removed. The radio plays CDs, has a USB plug, I did not used to check if it allowed a portable load (too bad, I should have). The product design is excellent as it is really small, to get an idea, the CD slot is seen almost the full width of the product. I did it installed by a professional so no idea of the trouble doing it yourself but the manufacturer advises.
