Hi,Hello,
Did you use an HK3 hardwire kit or an external battery pack? Do you power the package through the USB port on the body side or through the GPS mount? Do you use the supplied cable? What card do you use?
We suggest you use Guiformat2 to format the card first and see if it still happens. If it doesn't work, please try to unplug the rear cable.
Please let me know the result.
