Thread: About gmapdem.img file Express updated in Nuvi with 2015.10 EU release.

Hello, thanks for quick reply. Used gmaptool, very nice. As expected, the gmapdem.img file on my backup is identical to the new D2249750A.img file after map update 2014.40 and 2015.10. The other file I mentioned appears to be differentand a re herring. I have to ask the question, why did garmin tech support here in the UK not have a clue about this issue, nor would they admit to any issues at all and their final solution was to send me the same dem file as my backed up copy and teh renamed file, to rectify an issue that they denied had happened. It is ,so rediculous that we, the end user, should be doing the diagnosis and prognosis, for this multi-million pound corporation.

Anyway, from what I can see, the 3d terrain works fine, the only difference now is, that the dem map is missing as an option, so you cant turn it off form this menu. So, why did this renaiming of the dem file happen? and is renaiming it back to gmapdem the right answer, as has already been suggested near the start of this thread?
