Imagine this... All excited to pick up our new 2011 QX-56 a few weeks ago. I subsequently find out that 2011 Infiniti no longer offers support for call waiting on the iPhone. I missed an important call that I was expecting. If you're on a call and another one comes in, you'll never know it. No beep, no indication at all until you see the missed call in the iPhone itself. Our 2008 QX-56 had bluetooth call waiting, so naturally, I wouldn't expect to lose functionality with a new car. I went to Infiniti's website and my finding was confirmed. It clearly states that call waiting is not supported. This applies to virtually all 2010 and 2011 Infiniti cars. Prior years are supported. Hope this helps. This might be relevant to anyone considering Infiniti as a new car choice.
