Mods- feel free to move this to the correct forum, this is more of a "something I've learned" post... I was having trouble connecting my BlackJack (Cingular) to the Bluetooth and so I played with a few settings and was able to find something that made a huge difference! I originally had the BlackJack set to have an "auto-connection pop-up" which would ask me if I wanted to connect to the Prius' Bluetooth capability. Despite that I would tell it, "yes" it would connect for a couple of seconds and then disconnect, only to ask me if I wanted to connect again... so, in the settings>connections>Bluetooth>headset setting I turned off the auto-connection pop-up and now it works perfectly! Not sure why it wouldn't work well before, but this small change made all the difference! I was just about ready to give up on Bluetooth...
