Hello! I want to buy an Audi A3 in a short time, year 2006 engine 2.0 TFSI quattro. The car lacks automatic pilot and has a 1DIN audio system. If I'm going to take the car, I want to have a 2 DIN navigation system, but I don't see how I could install such a system on it. Is it possible to change the 1DIN cassette player with a 2DIN navigation? what would be the costs and what parts are needed? Has anyone else made this change?
