So long as it is a "blue-tooth enabled" phone, it will work providing stereo dampening.
In the Dayton area, I found the top rated blue tooth phone (a Nokia 3650) (one of several offered by T-mobile) works decently as far as a non-flip type phone goes in both of our 2004s LX470 & LS430. (Our callers don't hear us as well however in the LX470 compared to the LS430.)
While the phone is said to be the best blue tooth available from T-mobile (Sony Ericson is the other option), the buttons on the face of the phone can be easily pressed when clipped to your belt, etc., with you re-dialing your previous call. That is a disappointment. While
Verizon doesn't yet carry any blue tooth phones in our area although they are the best provider of service.
All in all, I'm disappointed in the limited selection from T-mobile and none from Verizon. Hand's free is nice, but your phone choice thus far is too limited.
