Ok, so I own an 06 S60-R with the HU-850 Radio. I read somewhere that it supposedly plays Mp3 CD's but it didn't work when I tried it. I guess the newer models have it with that feature?<p>If I were to swap out radios, who has an HU-850 that is capable of reading Data CD's? Do you have stock part #'s I should be looking for? What year did it come out of?<p>Most importantly, is that radio plug and play backwards compatible with another HU-850 that did not have that capability?<p>Thanks for your help on this.
