I found this great DIY on the Vortex:
The original poster installed a backup camera that's integrated into the rear trunk release handle of his '10 JSW. I guess it's a Europe-only option.
I would like to install the same on my '09 but was told by the supplier of the wiring harness that it wouldn't work. He warned that the trunk handle on the 2010 is wider and would not fit without metal fabrication.
Sooo, if any owner of a 2010 or 2011 JSW is reading this post, would you mind measuring the width of your trunk handle?! The one on my '09 is about 3.5 inches wide.
