Most of the heavier jobs are complete for now on RRS so I am currently planning a more sedate job which is scanning about to see what TV systems there are out there now at this time. I have been looking through the posts here and most are older posts and as tech changes so quick I thought I’d better get some latest tips of options of what to install.
Currently I have the DVD changer/rear headrest screens but no analogue TV, so I would like to add a TV tuner to view via the original screen on my 2007.
I see loads of 12V TV tuner out there for reasonable prices but need to know exactly how to connect a third party digital TV tuner to my original setup?

Is there any more up to date posts/guides out there that may be of use? Any links also would be appreciated.

The alternative is to buy an all in one head unit with TV etc; etc; already built in but would like to check out the original options first.  RRS 2.7 HSE Stornoway Grey
