My whole point is not to do any thing manually but just use what Garmin gives you.
To many users will be reading this things and want to try and update manually only because they can not wait to get the official message of an update.
There is not rush for any update The 4.80 only came Saturday to my 66. Even if it did not come yet that would have not been any problem. It does not stop you from using the 66.
So users have to be very careful what they try to do. I have read in many forums users screwing up their Garmin Units because they do not know what they are doing. Not saying you do not know what you are doing. But from what I have read over the years users always touch the wet paint even if the sign tells you it is wet.
I quote you:
If you make a copy of the unit’s internal drive, and name it Garmin, the Webupdater will copy the file to that instead.
It gets the current version from device.xml, so you can edit that, and even trick the Webupdater into thinking your device has old firmware to be sure it will always see the latest version.
Do you know how many users with get this wrong????
It wouldn’t matter because I’m talking about an ordinary USB drive.
If your Garmin unit has say 4.20 on it, and you copied it’s internal drive content to a USB key,
Webupdater would always think you have a 66 with 4.20, and download any available update after that.
The real unit doesn’t have to be connected to the computer for that to work.
It’s only if you copy the GCD file from that to your Garmin and power it up that it can use the new file.
If for no other reason, it’s a way to check a firmware update is available that isn’t on their web page.
I suspect it’s the way the owner of this site gets the updates to upload here.
Otherwise he has a way to enter USB mode to copy the file before the update begins on the device.
Either way, there’s no difference in the file that will be downloaded whether it’s direct to the Garmin’s drive,
or copied from somewhere else. All the WebUpdater does is check the version, download the latest file,
and copy it to a drive that it thinks is a Garmin unit.
There may be a problem of course if you try to update with a file for a different model, etc.
Incidentally, if you want to downgrade your unit to an older firmware version there’s nothing preventing you doing so,
so long as you have a way to enter USB mode and copy an older version GCD file to it’s drive before it begins an update
from any existing GCD file it has on it’s drive. that it may not have successfully updated from and deleted yet.
