I think I have made a major (as in, expensive) mistake. I ordered one of these: ( 10.4 Inch Tesla Style Vertical Screen Android Car Radio Dvd Player Gps Navigation For Buick Lacrosse 2008-2012 - Buy Tesla Dvd Player For Lacrosse 2009 2010 2011,Android Dvd Player For Buick Lacrosse,Car Gps Navigation For Lacrosse Product on Alibaba.com ) for my 2011 Lacrosse. It is not - as the listing states - Plug and Play. There are two connectors that went to the original base radio that have no matches, so I have no choice but to leave them loose. The cable that connects to the included backup camera has a red wire attached to either end. The best I can figure is that wire goes to the +12 volts of the backup light. The other end of the camera cable? I have no idea where to connect it. At the end of several days of trying to complete the installation of this thing, I have pretty much given up, and gone back to the original configuation. Has anybody else had any luck with one of these? I should mention that it comes with no installation instruction or information. And, if you try to communicate with the seller, you are not likely to understand them, because they really don't do English. Anybody have any experience with this type of upgrade?
