The K1 system works well...most of the time.The mini-USB connection on the DVR is very touchy, and is somewhat loose. I keep the DVR installed in the bike, and have never needed to remove it (touch-wood) to review incidents etc. As a result, after I start the bike, I always have to make sure that the rather dim red LED on the push-button doo-hickey is illuminated. If it is not glowing red, then I have to jiggle the UBS cable to the DVR to get it to start recording. Sigh! I have had the K1 installed for over one year and it kind of feels weird to not have it there recording my travels. Is there anyone else have issues with the mini-USB power connection to the DVR?
