First, you need to assemble the two parts, the part that plugs into the cigarette lighter and the part that serves as microphone and headphones. The two held by a magnet.
Operation is relatively simple. You pair your phone bluetooth mode with the transmitter. Then you assign an unused frequency to the transmitter (usually one must choose province and 87.6 in 89.6 in Ile de France) and finally you search with your receiver. Shhh disappears from the radio and the sound is clear. It's done everything is in working order.
With the phone, you can start the music that easily broadcast on your car speakers. Concerning the making of Appeal, this transmitter has this though, even if your cigarette lighter socket is not well placed, you can "tweak" the microphone thanks to the flexible neck and back toward you to an outlet Call easier (simply by pressing the button). At the wheel is extremely pleasant. I tried tonight.
Big plus, the transmitter can connect the charger to recharge the phone. It's really nice. That way, even paired bluetooth transmitter that even in music playback mode, your phone does not discharge.
Ultimately, an FM transmitter that allows you to have the handsfree function on the car while listening to your favorite music. In addition, well designed and thought out, it is easily manageable driving.
