And now, for my second post... (I'll stop counting after this )

After I followed danhams procedures, I noticed that in the downloaded Garmin directory there is a file called GUPDATE.GCD that was not in the files that I backed up from the Nuvi (I backed up all files.)

I then took the update files and moved them into my Nuvi backup folder, overwriting the same (but older) files already in my Garmin backup folder on my Mac. Do I need the GUPDATE.GCD file or can I trash it.

Thanks,
Steve

I may have answered my own question. I checked the files on the Nuvi, and the GUPDATE file was not copied over. Looks like it is not needed. I'll keep one around just in case.

Don't throw it away. I mean leave it there. Because it permits reinstallation of your latest firmware without the computer. This by pushing long-long time your on/off button until you see appear software loading.

My memory may be faulty on this, but I also seem to recall that lack of this file can be a factor when a nuvi keeps trying to reload the firmware, in error.

IOW, erasing this file won't cause that problem, per se, but might make it worse if another fault causes it.

Anyone else recall this discussion?

Also, there is no pressing need to erase stuff from main storage. I always caution against using main storage for lots of constantly-changing files like MP3s or pictures anyway -- corrupt your directory and the game is over (unless you have a good backup and a few hours to kill).

Rereading my original post, I can see how it caused some confusion, so let me try to clear it up to see if I can get the answer I'm looking for.

Here is the current status:
1. I backed up all files on my Nuvi to my computer's hard drive in a directory called Nuvi backup.
2. I downloaded the Garmin update for 3.8
3. I copied the Garmin files to my sdcard and rebooted the Nuvi as per danham and all was well in the kingdom, the upgrade worked.
4. I then moved the files in the Garmin 3.8 directory ON MY COMPUTER to the original Nuvi backup directory ON MY COMPUTER. In doing so, I overwrote the files in the Nuvi backup directory (In retrospect, a dumb thing to do, but its done.)
5. The GUPDATE file was not in the original Nuvi backup directory on my computer. I checked the directories on the Nuvi itself and did not see it there either. That was what prompted my question as to whether I needed it or not since the ONLY place it is found is in the Garmin 3.8 update folder.
6. I'm keeping it around since there is no reason to delete it. I'm guessing that the GUPDATE file MAY be used to manage the update process itself and is therefore not copied to the Nuvi.

I hope this clarifies the issue. Is my guess correct?????

Thanks,
Steve

Yes more or less. If you upgrade your in executing the (for ex.) 350-380.exe file from your computer you will find the gupdate.gcd in your Nuvi internal. For me it's better to have it there see my message higher up.

You know Dan, some people in another thread had to format their internal disk because of corrupted directory. I did that too. And the Nuvi started normally, completely formatted, without any file on it !!! I have my maps on SD.
But don't try this

Interesting. By "started normally," do you mean it booted OK and displayed the basemap only? No map? All maps? Is there a ghost in the machine [g]?

Yes, thanks. I understood your earlier post and that is a very neat idea. Didn't know the Nuvi could do that.

I think there is a visible part and a unvisible part. The USB-disk you can see (and format)and write MP3 and JPEGS, and a flash memory part you cannot write on, or only by upgrading and use of RGN files. I have Europe City Navigator NT on SD, without map it stops and says it needs a map.(This when Nuvi internal is empty after formatting)

The GUPDATE.GCD file is the file used to update the firmware. Before the release of 3.60 (Nüvi 300/350) this file was automatically deleted after the firmware upgrade procedure. Since Rel. 3.60 this file will be kept on the Nüvi (That is probably what Garmin means with "Changed to make update procedure consistent with other GARMIN products" from the changelog).

It does not matter much if you back this file up or not. It will be changed anyway as soon as you update to a new firmware and it is not used for normal operation of the Nüvi.

For those new to this forum, without FreeBird's pioneering work, none of us would be able to fix failed upgrades, update using a Mac or generally be able to function as informed nuvi-ers [grin].
