I bought this unit about 2 weeks ago, and I'm very impressed with the quality of the picture and build. It takes great video in the daytime, and also at night. The night time video did not meet my expectations, but I think I was expecting a little too much. You can still see things clearly at night, so if an accident happened it would be easy to make out who's fault it was. The brighter your headlights the better the night time video will be. It also records sound, and the quality of the sound isn't bad.
Configuring this thing is pretty easy except for the time. Every time I try to configure the time through the I-Road Blackbox Viewer on my PC it tells me invalid date. I set the date for a day ahead of what it currently was and it accepted it, but when I put the micro SDHC card back in the unit it reset the time back to 2012. It was frustrating, but I was determined to have the correct date and time. I spent a while trying different things, and I finally got the time and date to stick.
Here's how to adjust the date and time and make it stick. When you go to set the current time in the I-Road Blackbox Viewer on your PC it will say its invalid, so set it to a day ahead or behind what date is currently at. Go to my computer, and open up the location of the SD card. When you open it up you will see 3 folders providing you have used the unit. The folders will be config, normal, and event. The config folder is what you are looking for. Open the config folder and there should be two .cfg files in there. They are system.cfg, and time.cfg. Depending on the setting of your computer you might not see the .cfg extension, so it will just be files that say time and system. You can edit the time.cfg with notepad. DO NOT attempt to open the system.cfg with notepad because you will corrupt the file.
When you open up the time.cfg there should be one line that looks like this:
time=1404683400,lang=0
The number 6 you see is the day ahead that I set the unit to so I simply changed the 6 to a 5 and saved the file. Next I right clicked on the system.cfg and selected properties. When the properties window pops up set it to "Read Only". When you do this it will prevent the unit from changing the system.cfg back to what it originally was. I also set the time.cfg to read only too. When you put the micro SDHC card back in the unit, and take it out for a test drive it should display the right time and date now. My time was 8 minutes off, but I can live with that.
My unit was running the firmware version 02.00.04 and the I-Road Blackbox Viewer version was 1.0. Depending on your firmware and viewer versions you may, or may not experience the same difficulties in setting the time on your unit.
