this seems alright?

However nice it may look in the advert, these cheap video headunits are normally complete rubbish!
 
Ive just had a little scan through some reviews, seems that some people have a problem where the touchscreen stops working, but some people are raving about it.

Possibly give it a miss....
 
Defo give it a miss. I've had one similar in the past...horrible user interfaces, poor build quality and rubbish sound quality. Go with a brand for sure!
