This is my mounting in a 2010 Seat Altea XL. It took me a couple attempts of trial and error, mostly because the guys at Seat had tried to re-invent the vipers (thread about that issue
HERE). This is my setup. First off, the front camera:
I had an old cheap GPS-navigator mount dissected, the ball part was sawed off with just enough material left to work with. A small hole got drilled and with a screw I attached it to a piece of metal band, originally meant for construction purposes. The remaining joint, a little bit trimmed off, was united to the mobius base plate mount thanks to my best friend Mr Super Glue
A touch of black paint later - Voilà! The locking pins has been bent upwards, don't need them, Mobius stay firm as it is anyway.
Off to the car! The metal tongue has been inserted under the sunshade locking clip. The stupid plastic lid covering its screws did put up a serious struggle and obviously didn't want to come off at all, but with enough desperation and rough language I managed to peal it away. Sitting like this the camera is low enough to be just within the wiped area of the windscreen, yet not distracting the driver. The usb cable and adaptor seen in the picture has later been changed to a more suitable home made up-angle one (about that DYI-project
HERE) The cable runs invisible inside the ceiling panel, down the A-pillar and inside the door rubber to the fuse box located below the steering wheel. I did purposely save the ball joint. Like this the camera can easily be aimed or turned sideways to record any police interaction if I'm pulled over, or I can swiftly have the camera out of the car if needed. Later the metal tongue proved itself to sometimes produce slight vibrations depending on the quality of the roads and has been changed to a more sturdy one without all those little holes.
View from the outside. If it wasn't for the beige mirror mobius would have been even more stealthy. I thought about painting the mirror black to reduce the contrasts, but as it is a high-spec dimming one with sensors and buttons and indicator lights I think it's probably a wise idea to skip that project.
Lets walk over to the back of the car, which is a hatchback btw.
Using the same type of metal band, I bent it to something resembling a clip. One part (about 10cm long) is tugged in over the ceiling, the rest comes out like this. A nice little curve at the end makes it all work like a spring. It sits beautifully, the view is perfect and with the hatch closed it all locks up, there's no wobbling or vibration whatsoever.
Last picture: The usb cable goes under the rubber / inside the panel, and is connected to a 12V socket I never use anyway. The window is quite tinted making the camera virtually impossible to spot when I close it all up, yet the image seems unaffected. Perfect!
That's it.
