Thank you all for the feedback so far. Perhapsna little background on whynI ask to give it some more context..... When test driving recently I was very impressed with the Mercedes system. It worked flawlessly and was very intuitive to use, so after that everything else was very ordinary, so the test drive of the Bemmer did not score high on that point. Then when it came to purchase time I chose to look at what stock was immediately available rather than wait for a spec order. So with that, my mineral white 328 sport was a great choice but did not have extended connectivity, but that did not concern me at all. Now my thoughts have turned to 'if I could add it now, would I?', hence my question before researching further if it is possible.
PS. For those in Bris, I have a coding cable and s'ware setup arriving soon for anyone interested in coding.
