This is one of those stupid things, but if you go to the Becker North America site (as apposed to Becker Electronics), you can download it for free. It’s a bit hard to find at first but go to this link:
http://www.beckerautosound.com/
Then click "Whats New" and scroll down a bit. There will be a blue box with a drop down menu in it that will let you download any of the Becker manuals in PDF for free.
