Just to add to some of the comments, I have also been through all the Bluetooth devices witht he same lack of success. Very clever device and it normall packs up while driving so you get to risk you life trying to get a $100 headset to work.
Have also have the Echo problems and really have to say that the Phone aspect of this device sucks - hope they have some type of upgrades very soon.
We have a product that this machine is ideal for so I hope it all turns out - see
