I listen to my AUDIO.COM books on my automobile's auto sound system using a dummy cassete hooked up to my treo. When I did this with my Treo 600 A
phone call would over-ride my book and let me talk to the caller with no problem. Both sides of the conversation went through the auto sound system.
With the TRE650 when I receive a call while listening the call overrides the book, I can hear the caller but they cannot here my reply unless I disconnect the cable from the dummy cassette. At this point i usually lose the caller as I make the change to talking on the disconnected
Treo 650 as I must use the phone in its usual form and cant use the car sound system.
Anybody know a fix for this or a better software program I could buy to remedy the situation>>
