Hi, I just purchased and installed a brand new unit. Has anyone had issues making calls with their iphone 4? I got the phone paired up no problem, phonebook sync'd and all other functions(radio, cd, and Ipod/iphone music playback) regarding the unit seem to be fine. I can make a call out just fine... but thats it. I hear no dialing... when the call is picked up/answered I can't hear anything through the speakers/deck, no sound is being transmitted. The person on the other end can hear me just fine though. I've tried hard booting the phone, volume settings, updating firmware... I dont know what
