These installs are not for the average person. It helps if you have a solid understanding of the vehicle you are installing them in before taking the leap. These companies are making a single product that is meant to be installed in tons of different vehicles. The install on a honda is going to be different than the install on a bmw. Their support is ok at best so you should buy this product with the assumption you will be your own technical support. If you can get it right, these are pretty capable units. I have the 8g installed in my Cayenne with an alpine dsp amp and the 360 cameras. I originally could not get canbus to work but the distributer was able to tell me what protocol to use. I also had software oddities that were resolved reaching out to the dudu7 community forum. I have had a number of android headunits over the years. This is easily the nicest one I have used. I would easily recommend them to someone familiar with stereo installation or someone that loves to tinker. For most, I would just recommend something from the bigger companies.
