Re: Screen retro fit
The GC has active headrests, I don't think you are able to install monitors inside the headrest. However, there are many options to mount to the headrest posts, back of the seat, etc. I don't have any personally so can't make any recommendations, but I'm sure someone has a preference they will post.
2015 Billet Silver
2012 300SRT, 2009 Jeep SRT, 2006 Charger SRT
Too many mods to list for each, so let's just say a lot was done over the years.
