It's a decent camera for day time and the GPS feature works great and is accurate. The voice is great as well, very clear. I bought a 32 gig card to go in it so it does a good long loop. Make sure and buy a good card and not the knock off. The only thing I don't like about it is sometimes when the car turns off and back on again, the camera doesn't start back up. I'm using it as a fleet camera and this is a big issue because the drivers are not going to make sure it's on.Other than that and the fact that the night time viewing is not very good, is worth it in the right situations. If I was looking for one for my car I would save my money and get this one that's cheaper and works adequately. For my needs I just need something better for my 34 fleet vehicles. Even tho some ppl complained about the language thing, I didn't have that problem at all.Do not buy; unless you're into cheap dollar store quality in look, feel and function. Horrible user interface and mounting keeps falling. The suction cup is useless and falls right after placing it. (I am a senior engineer - I know little things about mountings). I had to use 3M double sided tape to keep it in place. Also the C bracket that is holding the camera too loose and camera slides off. Again back to 3M tape. The whole unit wiggles and shake while driving. I bought this for work purposes for a study, other members bought blackVue (yes more expensive but 10 folds better quality). The videos are poor quality and you can not shut off face camera. The map is in Taiwan, it does not pick up where the driving is taking place, I was driving in Michigan. Bad decision buying this camera, but company already paid me for it; now I have to justify throwing this camera in garbage and ordering a BlackVue. Please do not believe the 5 star rating unless by others - this product deserves no more than zero star. Good luckHas worked as described. The dual camera operate perfectly, night vision is adequate to see the streets, inside camera records only darkness at night if no lights are coming into car. GPS works well, though at times it proves to slow in connecting with GPS satellites.i dont know, but it seems it doesnt have a choice of what kind of video format you want to use while recording. it will be better if you can record a long journey without a loop.I cannot say enough good things about this camera. I leave it plugged into a power outlet ( lighter style) and it comes on when I turn the engine on and shuts down when I turn the engine off. This keeps the battery charged for any time I want to turn it on when my Jeep is off. Such as when giving it to a valet parker etc...Loved it until it decided to just stop working.. It would beep but no screen imageMy only issue with this dash camera is that I cannot get it to show the speed in MPH, only setting appears to be KPH.Works pretty good. The only problem I have is the speedometer display on the camera is in Kilometers per hour and there isn't a way to change it to miles per hour.Kept falling off the windshield had to glue it in to stay, and the video is grainy can't see any license plates.
