In addition, if you output it on the right speaker only (further away from the mic) you can get more volume, with less feedback/echo.
This was really NOT READY FOR PRIMETIME. There's a lot to be desired for this implementation...
Better noise canceling mic
1 button access to the dialer
a phone book that doesn't create multiple name entries for multiple phone #'s
It did synch well with my Samsung PPC - I dumped the entire address book into it, but it's still somewhat unusable. The caller ID feature doesn't work worth a damn, and voice dialing from the address book is barely usable. All in all, it's almost as usable as the Parrot CK3100 that I pulled out. I wanted an all-in-one package to eliminate extra boxes and wiring.
The most important part works though - it mutes the stereo so I can hear the phone ringing...
Personally, if the sound quality were better and the caller ID worked right, I'd be happy. But I really expected better from Pioneer's flagship HU, especially for the $$ spent.
