Installing in-car entertainment system
 

I have a 00 a8 4.2 quattro and it has a basic radio.
I want to install a DVD/touchscreen entertainment system
But when I went to 2 car stereo specialist shop they said
my car radio cant replaced,I'm not sure why,something
about the size of the center unit and the car model. I
was wondering can these systems be installed into my
model of car?
The system is a single DIN with
DVD/touchscreen/tv/Bluetooth/radio/cd/mp3/sat-nav. Does the
system need to be a certain size/dimension?
I was also wondering if I could install it myself?

im sure it is possible but it will require a substantial amount of custom fabrication and the replacement of the entire audio system I believe. You may want to check in the stereo section as well with another post with your question.... but i'm pretty sure it's out of the question unless you're just gettin an entertainment system for the rear passengers via headrests or a drop down...

thanks for the reply
The entertainment system that i want to install is a regular car stereo with a pop up screen,the stereo is the same size as a normal car radio but the screen folds away into the system when not in use
