Hi, I've had mine for nearly a month now.
So far, I love it. We have had about a month of relatively hot weather here in Vancouver, BC, Canada. Not LA kind of hot, but consistently in the mid to high 20's (Celcius). I drive a black car, so the interior does get pretty hot. My Blackvue kept getting blurry in the heat, but the DAS 3000 has not failed yet. Night footage is not that great, but I'd much rather have something that will not shut down on me or record fuzzy images due to heat.
One problem that I am having at the moment, is with the external GPS. No matter what I try, the time and date changes to the same time zone as Taipei? Whatever time zone that is the same as Taipei. I have no idea why, but I checked my world clock on my iPod and it matches the time and date of Taipei's time zone, LOL. I had the proper time zone display a couple of times, but it always reverts back to the other time zone. I imagine it is Korean time zone without daylight savings. At least that's my guess. It gets pretty annoying, as I have the dashcam hooked up to my Alpine screen. The speed works just fine. I guess I should check out the map feature........ I could be driving in downtown Seoul for all I know, hee hee.
Anyone else have this problem?
