Anybody had any experience with the Chinese Android headunits you see on eBay, wish and the like? They seem to be very good value for money but what would they be like? The only experience of a non branded headunit was some awful ebay £20 bluetooth thing that came in a 106 I had a few years and the sound quality was laughable. Would one of these units be the same? I don't expect show winning sound quality but I wouldn't be able to live with it being any worse than the standard vauxhall CD30 unit currently fitted to my car.
