Ok so... headlights the ones above are indeed A5 but they are pre facelift A5 so they dont have the bulge in them. They would go straight in with minimal faffing ...the 2012 lights however are simmilar to an automatrix led
you can fit them and use vag com to code them as the advanced drl lights with fixed corner lamp
as for tv..well I was lucky to have tv as standard if you post a picture of what is in your boot gubbins il have a look. But as far as im aware you need to run the Green Coax cable from the front all the way to the boot .. you need a different MMI brain I think and said tv box.. im not sure if you have the fiber optic most bus network cable or if you would have to run it through
Never be afrade of trying anything I had to battle running cables with an lpg tank bolted in the boot ! Not easy
on to ACC next and gearbox service
