I'm still stuck here, AVIC-D3 with CD-BTB200 all connected and working except with my Treo 750. I loaded Jetware and registered, but it still comes up Invalid Device. And yet, if I go to BT audio, it plays everything on there just fine. I reset the AVIC, reset the BTB200 and hard reset the 750, then reloaded Jetware.
Interesting point, Jetware is not showing as a program running on my 750.
Any ideas?
