Nuvi 2595 Question

**Seabee** · 23rd March 2016, 02:55 PM

Actually it turns out that a folder named Maps won't work but a folder named Garmin will. The Garmin Lakes file is a gmapsupp.img file and it shows up fine. The Garmin Topo 100 is also a gmapsupp.img file and it shows up but I have to do some tweaking on it. It's conflicting with my City Navigator NT maps. When I check it City Nav unchecks and vice-versa. May have to rename the Topo gmapsupp.img file. Maybe naming it gmapsup1.img. I don't know. Sometimes it's magic and you don't screw with magic.:>). In order to get the Idaho Topo maps to show up I had to remove them from the Idaho Topo folder and just install them individually as *.img files.

Delete "Garmin" folder on the micro sd and instead create a "Map" folder.

Your device can read from Map folder, any map file, with any file name with .img extension.

Spot the difference above...

You must have only one map checked every time to avoid problems (some topo maps have two boxes to check, road-submap and topo-submap, so then you must check them both).

Having overlapping maps selected simultaneously can lead to conflicts. When selecting (checking) a map, some automatically deselect (uncheck) overlapping maps that are found. Consider those maps "Murphy-proof".

Read the following very carefully.

Your device (and ALL modern nuvis) can read map files from:

- Device's internal storage/.System/gmapprom.IMG (City Navigator map, one and only)
- Device's internal storage/Map/any name.IMG (name can include numbers and spaces)

- microSD/Map/any name.IMG (name can include numbers and spaces)
- microSD/Garmin/gmapprom.IMG and/or gmapsupp.IMG

You don't have to use the "old" name gmapsupp, just rename your maps to their names to distinguish them.
Only very old nuvi are limited to just 2 file names: gmapprom.IMG, gmapsupp.IMG (and some of them gmapsup1.JPG).
Only those nuvis are limited to an 8-character name with no spaces.

Now think of maps as "layers", one on top of the other.
When you have installed two or more maps covering the same country/area, ALWAYS select (check) just ONE of them, to ensure that Where To searches and routing instructions are from this map ONLY.
If you select more than one map at a time, you'll see one map on the screen (the one that is drawn over the other) but you' never know which of the two maps you are actually using for searches and routing, plus you are an accident (crazy route/crash/shut down) waiting to happen.
Exception to the rule: some Topo maps, although are sold as ONE file, when a device reads them, it splits them to TWO sub-maps (you see two maps to select in Maps List).
One of them is the map with road and search data and the other one is a transparent or semi transparent map (drawn over the other) that has some extra topographic data (height or depth contours, rivers, trails, etc). Some Topo maps use this second sub-map for digital elevation data (DEM) in order to view the map in 3D mode on some models.
You can't select (check) only one of those sub-maps, you must select them both or none (if you select only one, go to map view, go back to the map list and you'll see that the second one is selected too by your device).

Garmin faced some problems with nuvi users in the past, that were using a Garmin City Navigator and a Garmin Topo map, selected both at the same time on a device (... cunning users wanted to view a nice 3D Topo map and use the vast amount of data of a City Navigator).
So what Garmin did is to limit our selection options at "a City Navigator OR a Garmin Topo map", one at a time.
That's why when you try to select both, one is always automatically unselected !!! There is no name conflict, it's the Garmin's way of not having crashed/bricked devices.
