I have a 2008 GL320 CDI (purchased 4 months ago) and recently purchased an iPhone 3G. Pairs successfully, phonebook downloads just fine. Only problem is that when dialing out, the MB screen says "Connecting..." but I can't hear the phone ringing. Once it connects, I can hear the other party. It's frustrating because I can't tell if the call is going through or not. Also, each time I make a call, the Audio Select on the phone pops up, asking me if I want to connect the MB Phone System, or iPhone or Speaker. It's defaulted to MB, but why should it ask me? Very strange.
