There is an article on here about installing 380GWX dashcam. The article also has a link to download the version 4.4 firmware.  However, there have been at least two revisions after that, that I know of - one that was installed on the dashcam I bought - 4.5, the other that was available for update from within the Replay 3 software - 5.1.  But after updating the firmware to 5.1, I had to fall back to an earlier revision due to problem with dashcam wireless connection and as I could only find version 4.4, I downloaded and installed that.  The dashcam works now, but Replay 3 is refusing to update it (an error occurred while downloading the update, check your internet connection - my internet connection is okay though), so I was after version 4.5 and 5.1 files (or any other intervening versions if they have to be updated incrementally one by one, ie if a jump from 4.4 to 5.1 won't work). Can't find them on Nextbase website, so a link to all firmware files for the 380gwx would be very helpful.
