The Mumbi has a rich feature set and I do not use the list of all the positive characteristics that have been mentioned here, because they fall short of miserable quality and functional impairments. In my case the device is working properly not even when the vehicle is stationary: The FM transmitter manages (the 1st sent to them GERAT) on any single frequency to produce a clear sound reproduction. We live in the highlands (Westerwald) and can receive some channels on the radio. No matter how weak transmitter is the Mumi in the "frequency gaps" so "oppressed" that a reasonable audible sound takes place. Unpleasant "Wellensalat" with ghastly nervigem whistling, hissing or transmitter overlays are the result of that will make playing an ordeal. When driving, depending on the broadcaster strength of HR, SWF or WDR, even the one of us continue entwfernten BR when driving that Mumbi-Übetragung is so disturbed that you're pissed. After two days of unsuccessful setting the part flew (including package inserts in microprinting) in the bin. UPDATE: Due to a spontaneous call the manufacturer and its desire to improve customer satisfaction, they offered me to receive a free replacement unit, which should be greatly improved. I gladly accepted the offer and received promptly and as promised a package with a new, improved Mumbi-high-tech product. What can I say: The newly completed 2nd unit initially seemed a significant improvement to the previous, completely unusable version to be. Now it has in at least one radio-air signal that is not continuously overlapped. However, in soft passages during the songs or pauses in a permanent, clearly audible noise and hiss is heard, which has lead to poor evaluation. If at least the transfer function reasonably clean, could perhaps evaluate the device as a "sufficient" and this risk 3 stars. Coupled with a remote control, whose top cover is flexed like a Flitzebogen, when you press the buttons and its range is amazing 30cm, may be referred to the execution of the product as a whole is insufficient. However, the absolute uselessness need after 2 days of use of the replacement device again be certified: While driving back permanent hissing noises and - beyond the pale - is declining. The only positive thing is the effort of the service department to satisfy the customers and the free replacement. Last Update: The supplier has promptly responded and even refunded the purchase price without hesitation. Service Contact friendly and exemplary.
