After installation in my Passat (2005), I realized that getting all the settings (Loudness, radio programs, annoying demo mode etc.) after removing the ignition key be released. On the web I have found an indication that in this case lacks the permanent plus and you have to replace the red with the yellow cable. I was very surprised that JVC has already thought ahead, and the red and yellow wire was fitted with a plug. Thus, the swapping went loose without tools, soldering iron and a lack of technical skill on the stage. A company that wants to think along and not their own standard by force, you just have to vote with 5 stars! The device is also highly recommended and absolutely versatile.
