Before you purchase this or any Parrot product do some research and look at the complaints on the Parrot tech site.... The manual it comes with does not even match the product, manual says to go to menu's that this unit does not have and emails to Parrot tech support are not answered with any usable information. Call sound quality is poor, connections are hit and miss, cannot hang up any calls except on the phone itself, can't stop USB music unless you unplug the USB, can't stop bluetooth music unless you shut the bluetooth off on the phone itself.... This thing is almost worthless, it doesn't do any of its functions well.
