Video setup in my 2003 C Class

First off all Hi to everybody as I'm new here.

I hope to find an answer here to my question

I have a 2003 C Class 220CDI with the Comand in it without the TV option, TV tuner from MB was just a bit to expensive for me

Now I would like to use the lcd screen and TV button of the comand to connect some other AV equipment like a DVD player, or even a small computer box with remote control for DVD/Divx/Mp3 etc....

Everywhere I read that there should be a AUX connection in the glove compartment but I can't find it, maybe it is hidden behind the MB CD Changer

So if some could help here to connect A/V equipment to comand it would be great.

Thanks in advance
