You should have phrased your question better... --index is only about address search. POI search is independent of address search. I'm not sure if there is an index for POI as well - but what you could do is use 0x00000 codes that are not searchable. Actually most 0x* codes are not appearing in the POI search. So try around until you achieve what you want. But note - on some units the POI might pop up in the Others category - while being unsearchable on other Garmin units... However -yes deactivating/activating a map only concerns map display. Neither address search or POI search can be switched off on the GPS unit. On 03.07.2014 18:16, Bernhard Hiller wrote:

Czesc Andrzej,

thanks for your hints. Unfortunately, it did not work.

Next, I downloaded a fresh extract from Geofabrik and created a fresh map without an index. I verified that the maps which come with the device do not have POIs (well, there are some: all of them are military or civil airports, but that's it). After copying the map into the device, all the POIs were present.

That means, the device reads the POIs from the tiles (?) or somewhere else from the map when no index is present.

I tried to add an empty index by creating osmmap.mdx and osmmap_mdr.img files from a small JOSM download, and then created the gmapsupp with the "normal" tiles and that index - that did not work.

An Oregon does not have an option to select the map for search (even not enabled maps are used!), despite its rather high price it seems not to be a "better" device...

Other ideas?

Kind regards, Bernhard

Hi Bernhard,

On PC index is a file with name *_mdr.img, you can remove this file form registry (probably together with *.mdx).

In a gmapsupp.img index is a subfile with name *.mdr. You can split img to subfiles, delete *.mdr and then merge subfiles back.

Better Garmin devices have option to select map for search, maybe Oregon too? Is there any "menu" button at POI search windows?

Thanks a lot for your hints.

--index is only about address search. POI search is independent of address search. Thanks for that hint. I did not know that.

it looks like it generates the "index" on the fly from the tile data. With the slow speed of the items appearing in the list, that likely holds true for the Oregon series also.

use 0x00000 codes that are not searchable Well, I could do so when creating my own map. But the situation is the other way round: I want the data of my map to be shown, but the data of other maps to be ignored (and these otgher maps use the "normal" codes).

Consequently, with the current firmware of the Oregon, it is not possible to de-activate the POI search of certain maps which are available on the device. A disappointing result, but at least I learned some things...
