It has good sound quality even though my speakers in the car need to be upgraded.

Overall the feature set and sound quality is much better than I expected at the price point.

great quality control in China

Sound quality is excellent

I am giving 5 stars because it is a great looking deck, good picture quality and easy to use.

The sound and and video quality is great, and it has a lot of nice features

This can be set to regular mode, so that it works as it should, but if ANYTHING drops the battery power, the factory default settings kick in again, which means DEMO mode, and you will see all of the different screens start cycling.

Although I haven't even installed this unit in my 2003 BMW Z4 yet, the fuse cover is already broken - as I attempted to open it to insert a 15A fuse.
