I also really liked that the adapter switches on as soon as he gets power. Many other devices have to manually turn on a hide which makes the adapter impossible. So I was able to back him in the glove compartment and must install thanks to the NFC stickers (for me it was a great anti-slip mat with 2 permanently attached NFC Tags) never actually ran to the adapter itself.
However, the supplied power adapter has been suppressed in any way and a noise-free reception of radio program impossible so long as the power adapter is plugged in.
I have built myself a interference-adapter concerned and firmly in the glove compartment.
