This is one of the most frustrating electronic devices I have ever encountered. The manual's instructions on how to program the MiniKit are kind of vague. There is no email response to help questions, and actually getting the MiniKit to work correctly took me several hours. The only positive comment I have is that the telephone help number in the manual got me back on the right track fairly quickly. The numbers from your cell phone have to be added one-by-one, after the Blue tooth device is connected. In using the MiniKit I found that the volume has to be turned Waay Up, in order to hear over road noise and a/c in the car. Once working it does the job adequately, however, the on and off buttons take some getting used to. At this point I would recommend using your cell phone "hands-free" option and save some money and time that could have been better used.
