well,what he said was pretty simple. He got it on Amazon, from here, from the authorized one, and registered it with the serial number on the box. he had no problems though. looks like my answer would not help you so much. :(
one of my friends got a dabonda on...maybe ebay, and he says good things about the dashcam. so i assume he registered it without problems. do you want me to ask him how he did it?
I own LUKAS LK-7900. And was looking for another 2CH dashcam for my wife and found this one, DABONDA MIRACLE DBR-4000F.
It looks like easy to use with 4" LCD touch screen. The feature I like it the most is a function called, E&M Messenger Function. The Miracle notifies when turned on, that...
Well, LK-7700 seems to be legit pretty surely. LUKAS website does not have a description of LK-7700, but they do have the viewer for LK-7700. BTW, day time video looks pretty good. I just like it's price. :) FHD LUKAS one at $139.. looks nice.
LK-290 for LK-7300G Smart looks tempting. I have LK-7900 ACE and am very satisfied with it. If I did not have any, I might try LK-7300 which is cheaper than LK-7900. BTW, why LK-7300G Smart has the additional body?
Is there anyone has LK-350 power cable?
On Vendors forum, I read a seller provides free gifts including LK-350, as well as an AV cable, extra mount bracket, and CPL filter. If anyone has used it, please share your experience!
As far as I know, err1 appears when lens have problems. It could be something like unstable connection.
I don't think SD cards would solve it by formatting or re-installing the FW.
