I got a replacement back from FineVu USA Co. and they attached a link to the latest firmware and asked me to flash it right away. It's possible the issue was resolved in the firmware at some point.
I was actually unable to update my device, as it wouldn't boot at all. But if, as you say, you are still able to update your device, then maybe this will help - these are the instructions I got from FineVu USA Co. when they sent me a replacement:
Firmware Version: 2.02.100
Release Date: October, 22. 2013
Major Changes:
Disable Auto recording (records for 30 seconds when the power is off) and reduce Standby mode from 30 seconds to 10 seconds.

Updating the firmware on your CR-500HD (short version):
1. Format the microSD card.
2. Load the microSD card with the 6 files found in the firmware zip file.
3. The CR-500HD will recognize the new firmware files and update itself on its next boot up; all lights on the device will stay lit for up to 3 minutes during the update.
Updating the firmware on your CR-500HD (long version):
1. Back up any important files on the dash cam to a safe location.
2. Leave the microSD card inside your CR-500HD and connect the device to your computer with the USB to micro-USB cable.
3. The device should appear in your computer as a “Removable Disk” or like any other USB memory card does. Right click on its icon and Format the card (Default FAT 32, Quick Format).
4. Download the latest firmware from
http://cdn.shopify.com/s/files/1/0223/3601/files/CR-500HD_Firmware_v2.02.100_eng.zip?1507
5. Open the firmware zip file and drag the six files into the microSD card
6. Unplug the USB cable from the CR-500HD and allow it to shut off.
7. The CR-500HD will recognize the new firmware files and update itself on its next boot up. At this point, you can choose to either re-plug your device to your computer with the USB cable, or connect it directly in your car. The device will boot up and all lights will stay lit for up to 3 minutes while updating.
8. The firmware file will now be installed and ready to go. You will notice that if you connect the CR-500HD to your computer via USB, the folder will now show directories as well as the configuration software. You can open the text file called “ver.txt” to verify the firmware version.
