I bought my ZT-T last year which was fitted with a Navall head unit and initially I was very pleased to have what seemed to be a system that seemed to be relatively up to date (certainly more modern than the radio fitted to the 1991 Mercedes 300E the ZT-T replaced!). Indeed the reversing camera (unfortunately intermittent and out of focus), forward facing camera, DAB aerial and USB extension socket in the glovebox but no DAB dongle, steering wheel controls and subwoofer plug in the rear suggested that a previous owner had been keen to have all the features of a modern ICE system.
However despite the many features of these units which would seem very good value for the money, the lack of a manual (hard to believe) or any direct support (I presume Radioguy was the person to go to previously?) leading to endless, and mainly fruitless, hours of internet and forum research suggest to me that getting to grips with these units is most probably a waste of time. Certainly there's a lot of frustration out there...
Does anyone have any suggestions for alternative, current units that offer similar functions that will not be a nightmare to install?
I would stick with the Navall but would like to possibly use Android Auto which would seem to require Android 5.0 or above rather than the 4.4.0 that the Navall I have seems to be running.
Any positive suggestions would be gratefully received!
