Hi everybody, I have a question for any electrical 'hackers' out there.
I have a great Seidio GPS Audio car mount that I originally bought for my Treo650. It's called the G4850.

Since I sold my Treo650, I have been successfully using this with my 755p. I had to remove the backing foam to fit it, but it works perfectly, and charges/supplies GPS information without problems.

My only issue is that the audio in/out is no longer supported. The connectors seem the same, the power jack is present, along with the 'data sync' connector as well...
How did the Treo 650 get sound? If anyone can help me get the 755p sound to the cradle audio outputs and mic in I'd be really grateful! Thanks so much for thinking about this-
