Just as a quick reply Ive done 100+ head rests, oversized aside. If you just put the factory screen bezel under the upholstery, removing the foam for needed depth, and if wanted (I usually do)removing the usual 1/2 flare around the shroud, and if the upholstery has what is common a 1/8" plus of padding can be scrapped off up to the bezel line, so that all that is inserted in to the screen beze is the vinyl, no padding, usually works on even the tightest bezel/screens
another added trick to make sure it goes in good is to make sure the cuts at the corners are near the edges, you may want to keep them longer but it will cause problems of pulling the vinyl in to the bezel, also use silicone spray to lubricate the vinyl before insertion, it will dry and the monitor wont slip out.
This all leaves a more factory flush look, with no gaps on the corners as can be seen on these surface mounted screens. any question please ask.
been doing this for 12 years.
There are no gaps in the corners, but this was only my first headrest screen installation. I don't believe there is any way the upholstery could have fit between the bezel and the screen.
what I meant was the far outer edges of the screen bezel, especially at the top is not touching the vinyl its hovering in the air(it looks like it in the picture anyway). Looks damn good for a first time, I havent had to many times where the material wouldnt fit into the bezel, but have scene it happen, If you want that really clean look what you do is use ABS or MDF to fabricate a new bezel that will allow for the vinyl/leather gap, takes another 1/2 of work but looks alot better, I dont even offer surface mount screens at the shop anymore. you just lay the screen on the MDF and put dbl stick tape on it to account for the thickness of the vinyl, then trace and cut, ABS is trickier you have to get 1 long piece and bend it where you want then weld the 1 seam.
Just trying to help.
Cutting the headrests and installing touchscreen monitors isn't that tricky really.
My original headrests wouldn't allow me to fit anything over a 5.8" screen, none touchscreen or vga. After having a think about it I measured up the rear headrests, as with most cars these days, these tend to be slightly larger and flatter than the front headrests (with Ford anyway). After some measuring, a pair of Linitx 7" screens would fit nice and snug.
Also I happened to have 3 spare headrests I picked up for a tenner at a breakers yard- not bad for oem leather headrests!
The pole design was also different so I needed to transfer these over to allow the screens to fit on the front seats.
I mask up the back of the headrest, trace a paper template around the screen bezel, get it dead centre on the back of the headrest and mark on the masking tape where I need to cut.
I then cut around the line with a very sharp blade, no real pressure is required. Make sure you round the corners! So many people cut an X from the centre then join the points up resulting in a hard square cutout. By doing this, you will end up ripping the leather from the corners while you stretch it- if you round the corners off this wont happen as the stress is spread evenly.
I made up a pine wood frame that fit VERY tight around the bezel, drilled some holes where I could screw the bezel tight to the wood frame once fitted. This pinches the leather between the bezel and the wood frame, making sure there's no gaps or movement- it's something that 99% of installers don't bother with and you'll forever be 'tucking in' whenever someone touches the screen or headrest!
Drill the holes in to the hollow posts if you believe you can fit the cables down them- with the Linitx screens I fitted this wasn't possible as the wires were too thick to fit in the hollow section. I could have split them down both sides but that's a huge job that I couldn't be bothered with! it was easy enough for me to pass the cable through the headrest and seat running along the outside of the pole. As I drilled the poles and fitted pins to prevent the headrests being removed/stolen- none of this was visible anyway as the headrest sat on top of the seat back perfectly flush.
People often cable tie the bezel to the posts, personally I believe that's lazy and ultimately the price is paid when you feel the flex you end up with after you've finished the install. It's best to secure either wood or metal between the posts and screw the bezel in to that, it doesn't take that much effort to do the job right the first time!
Remember to do some recesses for the screens fixing tabs (they need to flex back to fit the screen and remove it), best thing to use for this is a dremel sanding bit as it gives a lovely curved recess which leaves the wood stronger than a square notched length.
Here's some photos- please excuse the sawdust on the screen lol.
I know many are now putting the headrest frame/bezel under the leather, as I did prior to using touchscreens- however on this install I actually wanted to have the bezel exposed and I wanted it to be easily removable without scoring the leather which happens all the time with the other method. It also looked nicer with the bezel in place imo, fills the headrest better and gives it a better profile.
You'll never get a perfect match to your cars interior, the leather is of a poor grade and the screens are of a very poor quality (cheap chinese crap). It's up to you but I wouldn't bother buying a thing from a company like that, put the effort in and get the job right.
