A previous reviewer said: "I have purchased this kit based on several recommendations here. However, I have not figured out how to "hot sync" to my PC using this kit. Is there a way to sync using this kit? Thanks for any feedback!"It took me a while to find this out. To hotsync using a cable that does not have a button on it, look for the Hotsync icon on the Treo 600 screen, select it, and when the Hotsync program opens on the Treo, tap the large Hotsync icon in the centre of the screen. This doesn't seem to be documented in the Treo manual.
