Hey guys, I would like to throw this out there. I just installed a Z1 with a ND-BT1. When I make a call, I do not hear any ringing through the speakers when placing a call. Not only this, by the time I hear something the first "hello" or beginning of someone's voicemail is cut off. Its extremely annoying!! Does anyone else have this problem?? I have a Samsung t509 which I had hooked up to a Motorola IHF1000 handsfree kit which never had this problem. Any ideas?? Thanks in advance guys.
