The unit is decent in regards to the fact that once set up it works and all the cameras and antennas seem to function as they should. The 6.0 android interface is also pretty familiar especially if you are an android user however its obviously a custom ein radio rom. My main issue was fitting it into my 2003 VW mk4 golf, i bought the basic metra install kit which by itself fits well once the stock radio is out, however this radio doesnt fit into the plastic metra facia and the inside of the facia needs to be dremeled pretty carefully. Afterwards I had to remove the actual radio bezel and dremel that too. after 3 hrs of carefully dremeling and sanding i was able to get a decent fit. So the install was a bit*h, now the only other thing i haven't been able to get working is the mirror link via the provided easy connect app and my Android 6.0 moto x, so still working on it will update here if it works.
