JPHUGHAN - thanks for the quick reply.
Yobao - I also have an iPhone 4S with iOS 6, but not the M3 (hopefully its my next car). My 2011 328i Coupe was mfg'd in 10/10 and has the Combox option. Since I upgraded my 4s to iOS 6 I have been able to receive TXT messages, but not email. I'm upgrading the BT with the .bin file I just downloaded. I'll post the results.
