So I rarely write reviews but felt I had to for this.
The unit is great, easy to install, good for the money, good sound quality etc etc.
However, I bought this headunit for the USB input, and although it's lovely driving round with an 8gb USB stick of loads of music there is one flaw.
The shuffle/random is TERRIBLE.
Like AWFUL.
On my stick I have however many folders containing albums which makes it really easy to navigate through artists/albums. However, shuffle seems to shuffle the folders, but rarely, very rarely the songs... meaning 4 out of 5 times it will play the same song from an album. After driving round for a week or two you end up listening to a mere fraction of the music on the stick. And it's INFURIATING!
It's 2012! Surely someone can write decent shuffle software?!
If it wasn't for this, i'd give it a 5 star review, but as it is I would have chosen another product solely for this one defect.
Hope this helps someone :)
