Hello,

I am new to this forum.

I have also been victim to Garmin's complaincency and total lack of support and Knowledge of this update. FOr me, however, my DEM maps disappeared on the 2014.40 update. and have not returned, as I was assured they would, by Garmin, by updating to 2015.10.

I, am, however, lucky enough to have a complete out of the box, backup of my 3590LMT including the .sys file. And, Yes like you, I was able to identify that the gmapdem.img file on my backup was identical in size 310,392 kb to the the new D2249750A.img. We have identical twin satnavs.

I have been in deep discusion with Garmin Europe, who are completely unaware of this issue, Yeah right, and as long as the device is working theere is no issue and told them about my observation and my conclusions. They have now agreed to send me a new dem file, which is of no use, as it is not missing but renamed.

Anyway, from what I see on my 3590, in terms of graphics, the dem is working, just not visible in the my maps section. But you can still turn this feature on and off in the map settings by clicking on the 3d terrain option.

From what I understand of your post, it is a simple case of renaming the D2249750A.img, to gmapdem and back to normal. But, there is another img file similar to the D2249750A.img which is about 574kb which I think is also associated with the dem file, but, I dont know enough about this to.

Any ideas.

Thanks.

PS appolgies for this long winded first post.
