After a fairly fast delivery I unpacked the transmitter and was done only once from the optic. Glossy black surfaces and appears to be a good workmanship. Steering wheel remote control, two instead of another remote control, cable with two times 3.5 mm jack for connecting to an MP3 player were included. Then I had to but notice that the transmitter very loosely fitted on the gooseneck and the side buttons can be operated with the corresponding counter-pressure. Try the key failed with just one finger to operate on the loose seat of the transmitter on the gooseneck. The steering wheel remote control is secured by a Gummizugbandes on the steering wheel. This type of attachment is not strong enough to prevent the remote control turns off when you operate the buttons. In addition, the steering wheel remote control must "visual contact" to the transmitter have otherwise they will not work. The establishment of the transmitter is very simple. It provides on radio and transmitter just the same frequency. The transmission from the transmitter to the radio but is accompanied by disturbances. The narrower and higher are houses at the roadside the poorer the transmission. In an open field, the transmission is better but not good, more like a weaker radio stations. The Bluetooth connection to the mobile phone is not usable. You have to shout out loud so that the other person on the other end of the line ever hears something. I felt at the volume you need no phone. All in all, the purchase price is not worth it.
