Retrofitting Combox in E Series

[codemybmw]

Nice guide. I did back in 2011 on my E92. Was such a nice upgrade, but I never got around to doing the video out portion for iPOD out, however that feature didn't last long. Originally @vortex showed the way. I remember all these third parties charging big $$$ to do the retrofit and upgrade.

I think I still have a few multimedia or telematics combox in storage for sale cheap.
