Hello to everyone,

I have a problem with no solution coming to my head. Please help, as you are my last hope
Recently i have installed MFD C version, wich works well with my original cd-changer. Afterwards i have bought a non "B" tv tuner (with audi logo on it, it starts with letter 4DO..). I tried to connect it - everything works well - the mfd can find the tv/video, even without anntenas i can see some programs.
But my problem is that it is an unbelievably hard control of the tv tuner. I was sitting two hours till i figured how to change a program. I could not even find how to close some menus after opening, for example the teletext menu... So looking in the internet i found that this tuner is for nav+ from audi, which has more buttons, than the mfd. So i think that could be the problem - the lack of buttons. Well it would be not a fatal problem if i didn't connect a dvd player into AUX.. There is no button to change the TV to Video :O i know that in nav+ it's the Mode key, but there is no mode key in MFD. It is shown here in the manual
