I have the standard Alfa 159 stereo and while the sound quality is not bad the lack of Aux-In, phone preparation and Sat Nav is an issue so I have been looking at alternatives. there seem to be a number of cheap chinese all-in-one units on Ebay at the moment for around the £200 makr but I do wonder if they are any good. Has anyone fitted one of these units and if so what was it like? I bought an XTrons unit quite a few years ago which was Windows CE and it never really worked properly but the latest Android ones seem to offer a lot for not much. After all pretty much all car stereos and GPS units are made in China regardless of what the badge is.
