2010 ZDX problems with IPhone4
I am new to this forum and also a fairly new owner to a white 2010 ZDX which I love. I have encountered a problem that I am hoping to find a resolution for. When my IPhone 4 is interfaced with the ZDX, my handsfree options work just fine, however the sounds are turned off on my IPhone. Therefore, if I receive a text message, there is no auditory alert that a text message has come in. Can anyone tell me if you have had the same problem and if there is a resolution to it?
