hello there, i am after a bit of advise, i have done quite a bit of research but i have a few unanswered questions. i have recently purchased an audi a3 black edition 2010, 2.0 tdi, which to my surprise didnt have bluetooth. i have looked around and seen there are a few options to over come this. as i would eventuality like to upgrade my HU from a symphony 2+ to a RNS-E (163) it seems that the i can only go with the original , rather than the gateway pro or the fiscon, is that correct?? where is the best pace to obtain the latest oem bluetooth kit? the ones on ebay are older versions i'm worried that they will not work with my iphone 5. also does any one know a good fitting service in Bristol? thank you in advance.
