Finally got around to inistalling the K1 in my 08' GS. Running wires and mounting was simple and clean. The only issue I have, and its huge, is that the micro USB cables (even with the secure cable guide in place) seem to have poor connections. On my system, either power, or rear camera intermittently connect. My first ride yesterday recorded the morning commute fine. The commute home recorded only the front camera. Then it went into a recording loop when I arrived home. This system needs a connection like the C5. or the C5 needs 2 cameras. Definitely wouldn't buy this system again and wouldn't recommend anyone else buying one. Since the DVR itself isn't waterproof, I built a semi-waterproof case with fans. But with the intermittent, problems not sure it was worth my time. More reviews to follow with time.
