Good evening Sabri_ali00

If you have RSN 315 or RSN510
Or one where the above mentioned have construction form this goes in

But you must have a frame for the radio e.g.
this
Double DIN bezel 002.102S1-0

And take the cambus power adapter and the switch plus off.
Or buy a canbus adapter where it is converted but they are more expensive.

I hope I was able to help you Yours sincerely Audi2006
