This is awesome! Duane - much thanks! I have the latest version (with the disclaimer) on my Dash. Is there anything I need to do to prepare in advance for this when you roll it out?
The update will be done over USB. Due to age, the device can be a bit picky about the size and format of the USB dongle.
You'll need something that's 4GB or less in size, formatted as FAT (not FAT32). If you only have larger sizes, there's some info on reformatting a larger drive to provide a FAT partition here.
The update will be presented as a ZIP file, you'll need to unpack that ZIP file onto the dongle. You'll need to be sure that the unzip utility you use doesn't do "useful" things like replace line endings in text files, rename the files, etc., which some unpackers on Windows sometimes do.
