Thanks for the replies! Just wanted to make a quick follow up to both.
TBI, is it your understanding that the aux-in connector on a charger won't work with phone calls because the phone was never intended to be used that way, or because Apple hasn't released any compatible chargers yet (ie. do you think that option will be available as new chargers are released)? Did the original iPhone permit this function?
Bbotte, are you describing connecting a cable between the headphone jack and the aux-in connector on the stereo, or something different? I was trying to avoid having to make two connections every time I put the phone into the holder, one to the headphone jack and one to the power connector. I thought that using the aux-in line on a charger might solve that problem.
Thanks again for your help.
