i am nearly finshed with wiring it all up to the car unfortunately it started to rain so i had to stop doing what i was doing but, it a strightforward installation.
for me the trickiest part of the installation was drilling a hole for the joy stick and mounting the monitor to the base.
i used 5mm drill to drill a hole just big enough hole for the joystick to go in the hole then got the file out, to make it to a perfect fit then i used super glue to stick the joystick to mounting point, just watch out not to put to much glue to the joystick you don`t want to go on the joystick just the corner bit to make it hold to the monitor surrounds.
for the monitor i used thinist 3m double sided tape and used some duct tape hold it from the back like the picutre
