It was perfect for exactly 3 weeks and then the Display went black, so it's useless now, I'm sending it back for a refund! Otherwise read below...One minus is that there is no manual on how to operate, just from experience and playing around settings etc.The sound is Ok, I would love to hear more of the bass.SatNav is perfect and very accurate. I love it definitely.Another minus- there is an issue with SD cards and USB, unfortunately.This head unit supports up to 256GB of external storage, but isn't mentioned that it has to be fat32 file system and I had to find 3d party software to format my exfat 64GB SD card to fat32 (Windows doesn't allow to perform this action), otherwise there were just few songs playing, despite that I have copied around 2000 MP3 files and many videos on it.The installation was easy, though I needed to buy Radio antenna's adapter.And yes... I still haven't figured out how to answer the call, when the display isn't out ( possibly no way to answer the call).Anyway I like this head unit and would recommend it!

Sat nav don’t work and getting hold of Amazon for a replacement is a nightmare

This radio for my car is a good one. It has a high quality and i can receive so many radio channels. So i like the price too.
