For those who have been following this saga I'm quite unhappy with my hands free calling via the X920BT's Bluetooth software and mic. I bought a DNX-8120 today and plan to install it and test it with the existing mic in the exact place that it's in right now. This should give us a pretty good idea (more so than testing different phone IMO) as to if it's the mic or the unit itself. If it sounds better than we know it's the Pioneer itself. If it's not any better I will swap out the mic too and see if it gets any better. I'm waiting for a few parts before I can install so it may be a bit I wanted to give a heads up. In the meantime I want to do the latest software updates to the Pioneer and test it again as they supposedly address some issues that Pioneer knows about concerning the BT specifically. Others have reported little to no increase in performance so I'm not expecting it to help but at least this way I can test it out and we can know once and for all how the compare.
One other thing the my install manager buddy and I were discussing is the roll that mobile carriers play in the whole thing. I have had NUMEROUS BT units in the past and never had a problem but I also was using T-Mobile and various phones over the years. I'm not using a Droid on Verizon and he said that they have had some issues specifically with Verizon. I don't know how much weight I put in this yet because I don't see how CDMA v GSM would be a difference in the data handles via BT but I don't know. All I know is this exact Droid works flawlessly in a few other hands free navigation units I currently own and several I've had since Nov when I got the phone. I haven't had a problem until this X920BT and thought something was defective with this specific unit but then I read online that others with the X920BT were reporting some similar issues. Leads me to believe Pioneer dropped the ball on their software side of production.
I'll have more to report before long. Stay tuned...
