I installed the K1 last week and thought I would show some installation pictures.
Rear camera, hardly visible :-)
Front Camera: more on show but when looking at it head on you can hardly see it
The main unit tucked away in a storage compartment with all the excess cabling tied up under the steering column, the button you can see on the left, I used a power magic battery pro to prevent the car battery from draining, you can see it just on the right hand side.
All the cables are nicely hidden in the roof lining and, my only problem will come in the summer when the hard top comes off and the soft top is used, I will have to remove the rear camera and either not use it or find a way of mounting it.
I upgraded to a 128gb SD card and will try and post some recordings once we have a nice day, the image is slightly distorted because of the wind screens
