Quick question (i hope): My CD on my bose symphony II radio has gone faulty. I used to have my dension ipod connected to it and that no longer words because the fault with the CD side of the unit. My questions is: I see a lot of symphony II units on ebay for a range of prices but are not necessarily from a facelift 8L S3.........So is there a difference in them other than the fascia? (I can use my current fascia on a new radio just by swapping them.) So as long as the one i buy has its code, is there any reason not to buy say a Symphony II for an A4 of the same age? The connection look identical. Will all work with my Bose system or does the one i get have to have been from a bose system too? (surely its just using special pre-out connections for the bose)? Any input would be appreciated!
