Okay i will start a new one instead.
First you have to pry the end cap off, i dont have this one anymore, i just pried it off with the blade of my pocket knife, it just click off and on like so many plastic things do today.
Under that you will see the first screws.
Mine look a little different as i hit the test sample hard ( almost set fire to it honestly )
Unscrew the 4 Phillips head screws, and they and the next plastic cap should come off easy.
You are now set to pull off the "click ring" be careful with the spring and steel ball that do the clicking when you adjust the camera, face LCD screen up.

Next you you are ready to pry the 2 plastic shells apart to reveal the PCB inside, doing this will also make the 2 smaller plastic pieces come loose.
Those 2 little pieces are the trim pieces around the ports of the camera on top and bottom, nothing but the 2 halves hold them in place.
Now you have the PCB bare, leave it resting in the half with the LCD screen, you should now be able to get a good grip on the lens.
You should be able to do the testing for focus and test recordings with the camera apart like this.
After making your adjustment and securing the lens again it is time to put it back together.
Click the 2 half shells together remembering to put in the little trim pieces around the ports on top and bottom, it should just clock together.
Now its time to put on the click ring, forget the little spring and ball at this time, focus on getting the wire in the right place so there are free adjustment travel in the click ring.
When you feel the click ring is good you can tilt it a little sideways so you can insert the little spring and steel ball on top, to get them to slide in under the click ring you might have to depress the little steel ball.
you can now screw back on the plastic cap with the 4 screws, do note the notch in the hole matching a similar shape in the plastic below.
And finally click back on the plastic end cover you pried off first, and you should now be good to go again.
For test recording you can power the camera via the micro USB plug on the camera itself use a old phone charger or whatever you have with micro USB plug ( dont power off couputer )
The other part of the mount you can leave in the car windscreen its not really needed for this.
For connection to my TV i use a HDMI to mini HDMI adapter, and then use the HDMI wire that normally go to the box that control my home CCTV system, you can use the wire between DVD player or what ever units you might have connected to the TV with HDMI.
