Ok, this just gets confusing for me. The D2249750A.IMG I have on my device in the .sys folder, is absoulutely identical to the gmapdem.ing backup file I made when I first switched on the device when I got it.
When comparing both the gmapdem.img file on my backup, the gmapdem.img file Garmin sent me and the D2249750A.IMG I now have on my system they are identical to the last name, info, bit, byte, kb etc. It is safe to say that all three files are one and the same.
On this same thread it was metioned that, all that needs to be done is, to rename the D2249750A.IMG to gmapdem.img, so that the device is able to undersand and interperate the gmapdem.img file so that it shows up in my maps as a map.
As for zooming, the only difference with turning off the map layers as you sugget, is that the detail is less, in terms of shading and depth.
As far as everything else goes the device performs as it did berfore the gmapdem file was renamed.
My concern as to pasting in my original and totally identical gmapdem.img file, is, that havign two identical files, where only one should exist, albeit they have different names, is that this may cause a conflict withing the device. But I dont know enough about the way these programes and files interact.
If I had a spare devcie I would love to play with it and confirm one way or another what is happening. As there are a lot of people out there who believe that he file is gone, or are totally oblivious to anyhting that has happened.
I seek enlightenment and hope I do not appear as argumentative.

Just leave the file in the .system folder and rename the file and it will work fine. (Don't add any more files)
What are you afraid of anyway ?

The comments made by Ellinas and you have bared this and my assumption out. What I am concerned about is that there have also been comments on this topic which have contradicted the tain of thought, that this is the DEM file and just needs renaiming. But, two trains of thought here is my concern. And I am worried about messing with my deice, before I go away.
But, it is more likely than not, that renaiming and returning the file it to it's original form, dem name, will solve all.Last edited by Grumpier; 6th July 2014 at 05:07 PM.

Holy crap, I stand totally corrected. Could not resist changing the name as I knew it had to be done. Anyway, Yep, definitely it was not working. As soon as the device rebooted there was teh EU DEM Map, in the my maps where it should always have been, looking good. But, the real revelation was going to a moiuntain range ion the Austrian Alps, now before, the terrain mapping was pretty damned good. But now, behold, the mountains have real peaks and troughs, truley great.

One more thing, why was Garmin UK so, unknowledgeable and so useless? This really was such a simple thing to have to do and I don't believe for one minute the real techy guys, wherever they are in the world, didn't know. A simple memo to all service centres, saying, rename the file. How difficult is that. Rant over.
Thanks people a nice friendly forum.
Ps. Dasilvarsa it looks like I misread the last line of your post

As with all large organisations, it's probably not totally fair to judge them on the failings of one or two staff but to state the obvious a chain is only as strong as it's weakest link. I've had email exchanges with certain service droids who were obviously thinking about their next beer-break rather than the problem. In your case, someone hit 'crappy-response #3' rather than even think about what's actually been asked i reckon. Originally Posted by Grumpier

The lowest of the lowest newbie trainee customer [dis]service officer at Garmin should and would also know that, along with the fact that if it's not appearing in map info then it's not working. That's because it's Garmin File Naming 1.01 for 3xxx nuvi series and related. If i was in a regional service division and got a memo from on-high saying anything more than a warning that replacement dems are being loaded to .System named other than gmapdem [such as saying don't forget to tell customers to either rename it or move it to a Map folder], my reaction would be 'Thanks Capt. Obvious!'

Just to Add on Nuvi 3490/3590
If you create a folder in the unit memory named /Map you can copy the dem map to it with anyname.img and it will work.
