Test Pioneer AVH-291BT

I have this product since few months on my Mazda 3 2006, overall it's a good product, sound quality is very good, image quality also.
The pros: ease of talking with hands free calling Bluetooth, they hear us very well.
Sound and picture quality.
The cons: impossible to change the background image, the blue colour on the left does not change.
The Bluetooth fonction takes a long time to star, sometimes I have to connect it manually because it does not automatically connect with my iPhone 7.
The cover album is not displayed (except when the phone is connected to USB).
The playlist fonction is to improve, it's not compatible with the iPhone at all, It's better to choose the playlist from the phone and not from the DVD player.
Overall, I rate this product value/money: 6/10
