Im in the process of buying a 07 A4 2.0T, and it comes with the standard Symphony II radio, and i wanted to put in the RNS-E Nav. I was wondering if i was to put it in would it be plug and play or do i have to rewire my whole car?

 

i think he is just talking about swapping stereos u should be able to just switch them out i think. Might need a new harness but other then that just make sure u get doubledin. I thi nk there is someone on ebay who seels them for under 800 which is a steal.
