96 A4. Looked inside my trunk on top, where the holes are near speakers and noticed a white computer style cord, similar to one used for a monitor. It says Dell on it. What the hell is that for? It appears to be hard wired on one end and not connected on the other.

 

Hook it up and see what happens.

 

pix might help just a tad bit

 

Buddy of mine has a Windows PC in his A8 hooked up to a double din touch screen radio, so it IS possible. Still have the stock radio?

 

Hey everyone, thanks for the replies. Its a Radio Shack cord, not Dell and I ended up calling the guy I bought the car from (original owner for 16 years until I bought it) and he said it was for his MOBILE PHONE he had installed back in the day. Holy ****-how the times have changed.

 

Many A4's came stock with mobile phones. There is a cut out you will see in the center console.
