I'm going to go with Blue and Red on this one (White...White...are you out there? ). I had a terrible time with my iPhone (first the 3G and then the 4G) on this bluetooth. Same issue - 60-70% of my conversation cut out and it was usually worse for the people on the other end of the line. I went back and forth with my local Nissan dealership, who felt it was the phone. Finally, they took me into the service bay and had 4 different mechanics pair their own phones up with the car and make a car with no problems.
Around that time, I upgraded my OS for the 4G and that particular upgrade (not sure which version I upgraded to at the time) seemed to resolve most of the issues. Now, mind you, you're still going to get a lot of road noise no matter what you do, which is going to sound worse for your listener, but the change in OS definitely resolved the cut-out issue. You can try to sound-dampen your Z (like I did) but just keep in mind that most sound-dampening techniques aren't going to solve the problem, only reduce it. I did get some ambient noise improvement (mainly from the road noise) from the sound-dampening material I used (which I applied to the back, firewall, doors and floor) but it's still far from quiet.
Long and short of it: it may very well be your phone and even if you resolve the phone issue, your listeners are still going to have to decipher your voice over the pretty high road/tire noise that isn't going to go away. But I can say that I am now at a point where the people on the other end of the phone don't have a major issue with hearing me anymore, even on the freeway.
