I'd love to see pics of your 21st century improvements. i don't need TV in headrests but curious about the upgrade.
I rectified the problem by binning the entire outdated COMAND and D2B Fibre Optics System and installing the ERISIN Android unit with all the goodies including TV and DVD Headrests with individual IR Headphones, all installed to factory standards ......................
Absolute belter, I can recommend the Install to anyone who has the nouse and patience to do it correctly !!
As a bonus it tastefully brings the whole Cars interior into the 21st Century 😉
