I replaced my K2 on my motorcycle with a K3 and moved the K2 into my Ford Edge Sport. Now a SUV is a lot bigger than a bike so I had to extend both cameras (the 1.5M and the 3M) by adding 2M worth of USB-C extension cables. And it worked!I designed some camera mounts in about 30 minutes for the front and back camera, they are super clean and keep the Ziptie "lock" hidden in the side. I ran all the wires in the headliner/A Pillar. And hid the DVR on the backside of the glovebox. I tapped the constant 12V off a line from passenger fuse panel, and the trigger wire off a 12V accessory port (that powers off 5 min after the ignition turns off).
I also 3D Printed a clasp to hold the USBC Extender onto the INNOVV camera connectors since they will be hidden in the headliner. I clipped both into the bracket, and then wrapped the bracket in electrical tape.
The heatsinks on the DVR are from when it was on my motorcycle, but works well back in the nook it is stored in. No GPS connected yet, I am trying to figure out how to get to the underside of the dash somewhere to secure it... but so far that's not as easy as I hoped. The DVR is currently held in place with VHB tape, but it is going to be industrial velcro once I get more in.
