I would strongly advise against motorcyclists them, even to plug the adapter directly to the adapter in a power socket on the handlebars or wherever. Obviously by vibration itself operates the operating unit from the USB port on the socket adapter. Uses definitely the included USB cable as a link between the control unit and adapter, because this connection is flexible and therefore not susceptible to vibrations
My unit also comes in a quirk that I have first filed under warranty. The Mini DisplayPort is indeed readable displays, but Fehlfarben (orange one half and one blue) in the background. Moreover, it is not quite straight under the cover. I have arranged with the seller at a discount (5 euros - were quickly reimbursed). So how do I use the device, I look anyway as good as not on it.
So far, so bad ??? Nope, there are also positive! Namely, in the transmission of the FM transmitter!
My Goldwing has an American radio that obviously related to the separation efficiency can not keep up with the German or European standards (resolution in 0.2MHz increments). By that I meet while the standard transmitter, but it falls relatively hard to find an unused frequency on which the transmission can operate. In fact, I have as yet to be determined with us 95.3 the best frequency, but you can hear on the radio with my board thoroughly any channels, penetrate the meaning. After all, so that you can understand language reasonably. My fears that thus the "Project FM transmitter" has failed on my Goldwing, turned out to be unfounded. If the FM transmitter is activated, it takes a 3 or 4 seconds (in which one something will notice from a radio station!), But if the transmitter has been established, which is a clean transmission in which one notices, no more interference. Ds I find quite amazing. So far I have made trips within 75 km and have never experienced something of a failure by radio stations.
The transmission quality .... well, we are talking about operating on a motorcycle with wind and engine noise. HiFi I would not expect from the device, but on the Mopete enough quality from perfect. And even then, if you are not driving, but can be showered with a break in a parking lot of a little music. How far it would just work with quality in the car, I do not know. Never tried, because I do not need something like that.
