I have the Treo 650 with all of the new updates on it, including the
handsfree adapter.  I still can't get it to work, the Device connects
to the CK3000 but upon my driving on the freeway it the sound on the
other side of the phone horrible.  Ithe other person can't hear me at
all.  I checked all the connections recently but nothing going there.
In fact it works perfectly when stopped but as soon as I start moving
it is horrible.

Any Ideas?

Thanks

Trent
