From what I've seen on the web the internal wiring is different. I've checked out the charger and it looks like it will fill one of three needs - charging the device. Pausing the music and getting the phone to talk to COMAND via a dongle or BT simultaneously appear to not be addressed by the adapter (according to what I've read of the adapter by users). My COMAND will not pause the iPod app in my iPhone 3G when a call is taken or made.
Can any purchasers of the adapter confirm that the iPod app is paused/restored during/after, respectively, a phone call is taken?
