Hello Heinz-Fahrer, I am just about to get a used Heinz. And it should be upgraded a bit. Since it will be the family car for my wife I would like to retrofit a Navi and a rear camera. With us in the area always many children jump around and because of the Heinz format can easily be overlooked. I want to avoid the risk. Does someone know a good solution for the double DIN shaft, which then also looks good optically? Have a few tref when googling VIGO Jewellery Does anyone have any experience with it? Or are there any other alternatives that remain in the frame? A detachable AHK and upgrade to the heater are also planned. Maybe there is someone else who has tips and prices for orientation (parts incl. installation). Thanks and lots of eGrüße, Sascha
