I have discovered that the Palm right angle audio adapter does not work right with my G4850. I do not get stereo sound with it. If I change over to the Seidio adapter (I like it better, anyway), the problem is solved. Strange problem. Since both adpaters work with the 650 itself, I would think that they would also with with the cradle. Also, interesting note, my old G2500 has a typical audio plug in the bottom where it picks up the audio through the headset jack. The new 4850 apparently picks the audio up through the multi-pin sync connector as there is no audio plug there. Hopefully this will help preserve the fragile and unreliable headset jack on the 650.
