Hi,

I've been looking at options to add a rear view camera to my 2015 Cayman base with CDR31. I saw this cool video of a mod that implements iGo nav:


I've been looking around and so far I've found this multimedia video interface module that adds 3 video inputs to the CDR31 unit. Prices vary from a few hundred dollars for the module to $1600 for shipping the unit to Nav TV and them doing the mod:

I was wondering if anyone here has done this mod, specifically how well it works for a rear view camera, and what would be needed to add iGo and get it to work like on the video above.

TIA!
