Although the adapter works well after I modified it, it would be a lot better if the speaker was not part of the cigarette plug-in. It sticks out so far that it interferes with other car functions. The speaker should be separated so it can be mounted away from where the cigarette lighter is. In one of my vehicles, it sticks out where it is regularily kicked by someone in the passenger seat, and in my other car it sticks out so that I can not use the beverage holder. In my third vehicle, it interferes with my shift lever. I had to buy a cigarette lighter extension cord so I could lay the unit in my center console. Other manufacturers have designed much better adapters for their phones. If I had know this was what Qualcom (Kyocera)had, I would never have bought their phone. I live in NYS and hands free operation is required by law.
