* USB port that currently hangs a 16 GB memory
* Ordinary Speakerphone
* (No superfluous CD drive)
* AUX-In
This is already the biggest selling point.
Also for the radio speaks, that it is good expandable, eg with three separate line-out port and the remote connection for any existing steering wheel remote control (which can, however, an additional adapter required).
It is operated via capacitive sensors, so that the radio really has no moving parts. It takes some getting used to something only. The "wipe and scroll function" You can soon appreciate. Dear would indeed have me dial, but you can not have everything.
Especially for convertible drivers and vehicles with sliding roof, it is good to know that the display on höschter brightness even in direct sunlight and with sun glasses is still easy to read.
Navigation through individual directories is as with most radios is a bit awkward; The limited number of control buttons and a small display make it easy not to that one browses through comfortably large directory hierarchies. I have trained myself to create for optimized music style settings a folder at the root, there must store and so only navigate by "music style to style of music" the title. For me it works. :)
The speakerphone function is straightforward, mobile connect (the PIN you can set the radio and it is usually 1234), and start calling. The external microphone does his duty satisfactorily, but sometimes leaves too many by noise. My cell phone may well A2DP and connects with the same as an audio source - here you have to watch, because the phone like jostles as source forward; After a phone call is to be made with the MP3 from USB memory, but the phone will be music player, even if just nothing is played.
The AUX-in can be used if you have another MP3 player case which can not be controlled via the USB interface. There are MP3 players, giving the identify themselves as storage device, this function simply as a USB flash drive. iPods can be via the USB port even from the radio remote control. Otherwise, the AUX-In is a good bridge to a perhaps arising Car-PC in my case.
All in all a good radio and at the current price of 99 euros an absolute Kaufempehlung for anyone who needs anyway a speakerphone and has already thought about it, to modernize its radio or, like me, to replace a defective.
5/5, because it may be exactly what I need.
