hi guys, I'm also looking for a way to get into the hidden menu of the NAC (3d Connect Nav) Peugeot. My car is a 2008, with CarPlay, Mirrorlink and Android Auto. Now compared to what I saw for the KIA, I would try to figure out if there is a chance to enter the system that is declared Linux, and find a gateway like an android virtual emulator, on which even turns android auto, to install other applications directly on the multimedia of the car. The only 2 codes we know are: 1111 1122, the first for spylogs, the second one gives us a series of info on the system, but apparently they are only legible and there is no way to get inside. In practice using the code 1122 the first time also gave me only info on the radio, but then typing in increasing order the following codes and typing 1122 again, for several times I have drawn many other info. I took pictures that I would like to share with you to find out if there is a chance to find a way.
