For little money you can using this FM transmitter his music from USB flash drive, SD or Micro SD card (with adapter), or directly from your phone to be wirelessly stream radio. To do this (which just in the cigarette lighter is plugged) is the unit one channel, and sets it on a program number of the car radio. Already you can hear his music through the speakers of the car radio.
You used to a memory card or a USB flash drive, you can even the FM transmitter the songs forward back, or pausing switch. In addition, the transmitter, in which pieces you left off notices.
When using music from your phone, the connection is established to the transmitter via the supplied small audio cable. Here one must, however, make the control of the smartphone.
If the first connection attempt, the radio does not reflect the music, you put the best an SD card from which you know what kind of music is it since. Then choose a radio transmitter button and lets the radio scan the frequencies. If you arrived at his music from the map, it saves this place.
At first I was a little surprised that the music from an SD card very well, unfortunately, much too quiet came over the phone. This was not on the transmitter, but, as it turned out put, the program with which the Smartphone happening music (in the case of "power amp"). After I had this set to my listening habits, the music sounded good again. In addition, you can generally try a little more at the sound of the radio in the "Setup", which sounds better. If this is so first so somewhat dull sound, not to assign the transmitter to blame, but first time to tune the sound in smartphone app and Radio Setup.
The sound quality between a directly integrated card reader and this streaming version is already a little bit different. The listening via the transmitter at a little "dull". When the but can not be compared directly with one another, you will barely notice. Finally, the device should be so used where there is just no other way.
In summary, we have here so 3 music inputs: memory card, USB stick, audio cables - as well as another USB input directly on the plug, for example: for the power supply of the smartphone, or any other USB device. The control panel is mounted on a flexible base which can be bent in all directions, so that he never bothers. (Tried in a current VW Passat) He looks quite modern.
Given the low price and added value thus generated the car radio without any additional conversions, are 5 star more than justified.
