Loving this product so far. Question is: I'm a dual-sport rider and often take my GS Adventure offroad. How does the K2 hold up in rocky, rough riding environments? Heading back to Baja next month, and I would love to have it fully functional but I'm considering leaving the DVR back at the hotel. Advice?

I just completed a 14,000 Mile trip through the US, Europe, and a good deal of Asia. The entire trip, the Innov K2 was running, and capturing video. During this timeframe, my Sena Momentum INC Pro helmet's camera failed, so I was left with just the Innov K2 to capture my trip. In my case, I ride a 2015 BMW GSA, and the control unit for the K2 is installed under the seat, attached to a power distributor. The unit was installed at the BMW dealer in Charlotte, by a Tech that I really trust, and who did an excellent job. First of all, this thing (the K2) was bulletproof. It started and stopped, just as expected, each time I started the bike, and it never missed. The video quality when riding more slowly, was exceptional, but the quality when riding faster is slightly less than perfect, but still very good, and certainly acceptable. I used a 256 GB SD card, class 10, and I never completely filled the card, although we rode some days, as many as 16 hours, and 400 miles. Pls keep in mind that riding in Russia, Kazakhstan, Kyrgyzstan, and China will be on severely compromised roads, so our average speed was lower, and a 400 mile day is a very long day. While I love this camera, there are a few areas that need to be addressed. 1) I needed to have a set of tweezers with me at all times, in order to remove the SD card so that I could download the video. 2) The spring mechanism that holds in the SD card is strong enough that, on one occaision, it shot the SD card across the chamber that is under the seat, and the SD card ended up lost, somewhere in the body work of the bike. 3) The rubber cover that covers the SD Slot is too fragile, and it broke. This rubber piece has a tab on one end, and from opening up the cover, and closing it twice each day, the rubber piece broke, and made it much more difficult to get at the SD card. I'm going to need a new rubber piece sent to me. 4) Because the connector ends on the camera are as large as they are, the installation onto the bike was more complex, and more costly than I could have imagined. It was simply not possible to "slide the cable head through the cable channel on the bike", so the tank had to be removed, along with all the body work, in order to run the wires properly, in the wire harness channel. 5) I was unable to get the unit to accept the latest F/W upgrade, so I'll need to figure that out, once the bike arrives back in the US. 6) After installing the new app on my IOS device, I needed to delete the app, and reinstall from scratch, in order to have it connect to the WiFi network broadcast by the K2. These issues are relatively minor, but a bit annoying. So, they need to be fixed, but we cannot overlook the conclusion that this camera system is fantastic. Numerous times during the trip, someone would say to me that they thought that I did something, or wanted to know if I recorded an event that happened, and because the camera automatically starts recording, my answer was always yes, and I used the video to show what happened numerous times. I also used the video on my Blog, on a number of occasions. So, if you're interested in seeing the quality, you can visit www.motocliffnotes.info and look through the videos. You'll quickly find those that were recorded using the K2. And finally, because the front and rear cameras record to files, which are started and stopped within a 1/0 of a second of each other, I was able to easily build files which had picture in a picture, using Adobe Elements Premiere 2018. You really should look at some of these videos. The F+R views are compelling. This system is awesome, and I can't wait to use it again, for my next trip. How do I go about getting a replacement cover, for the recording unit? Sample videos of PIP https://www.youtube.com/watch?v=3kHYN1EyoWU https://www.youtube.com/watch?v=J-KbJL4oOa0

Would it be possible to have the DVR clock use Zulu time/GMT? I'm a 24-hour-time type of person. I would rather the system time and filename timestamps were in 24-hour format, vs. remembering whether DST applies or not. This would also eliminate timestamps that are an hour off, because DST changed but I haven't connected the DVR to the K2 app lately.
