The display is really great, nice that I know with what channels I just need to synchronize. Just when connected to my S5, I can somehow not change the frequency on the device except by current caps .. maybe I'm too stupid for that. If the device is not purely down somewhere in the cockpit storage with other stuff, my interlocutor understood me very well in speakerphone. I also had no dropouts or anything. In the area of Mannheim, the frequency has 88.5 very good fit. The transmitter also suppressed, provided music on your phone is going very well, the noise sounds or even the intermediate talk from the transmitter moderator. The connection to the phone was easy. Everything works very quickly. Also nice that I can invite the smartphone at the same time, here was thought along like TuneLink. Now the unit has to prove only on long time. So far I am very satisfied.
