Improvable but are the plug, the three sockets and the LED on the adapter. Inserting and removing the adapter connector requires at least the Golf IV and Polo 9N larger - in my opinion, too much - effort. In contrast, the three adapter sockets have not all introduced plugs sufficient support (the plug of a tried out by two USB adapters that fit well in the original cans the above vehicles, jumps out of the cans of Avantek adapter by itself out). The blue LED is so bright that it literally disappears when driving at night, even when the adapter outside the viewing direction is stored in the center console. Remedy against the glare I was ultimately only by sticking a dark-colored Filzgleiters possible (white adhesive labels are largely white felt pads and silver gray "Duct Tape" partially irradiated).
