This add on device is an invisible system allowing your car steering wheel buttons to communicate with hands free kits via the UNIKA integration.
Where there are limited buttons on your manufactured steering wheel then a combination of presses can achieve the different functions. There are four modes, where Mode A is for four steering wheel buttons, Mode B is for five, Mode C is for six and Mode D is for seven buttons. This allows the device to be compatible with different manufacturer steering wheel designs.
Generally buttons have multiple functions depending on what the kit thinks you want it to do. For example you will use the same button to select a track as to accept a call, and again as a long press, to end a call. It takes a bit of getting used to, and is not for the faint hearted, but once you learn the sequences they become second nature.
The Parrot MKi remote will always be easier to use, especially for navigating menu choices when playing music. The choice is yours to either use the Parrot remote in combination with the steering wheel controls (e.g. steering wheel controls to receive, End and redial numbers and the remote for everything else) or simply leave in the box and rely solely on the steering wheel buttons to do everything.
