Garmin officially lists the limit on the Oregon to be 4000 segments. Based on testing the Oregon can handle somewhere between 4000 and 4229 map segments. This limit applies to the sum total of segments contained in all .img files loaded on the Oregon including the built in maps, it is not a per file limit.

I use a 16GB card. Have to delete some maps. Then I can see it on Oregon. I think it's a limit. I have Norway Premium 1-11, Norway Experience 8-10, Sweeden, Denmark, Swiss and BlueChart HEU800X. Think this is the max. Have to buy one more SD card to have for vacation:-) Thank alot for helping.
Maps number limit in Oregon , in 62 is 22 ,Basemap, timezone, gmapprom,gmapdem etc
I think, you should try to deactivate all maps in your Oregon Garmin device other than the actual map you need and the basemap so far. So it should work properly.
According to my experience, there will be conflicts in keeping activated more than 2 maps at the same time on the device. If needed next map, you may deactivate the actual and activate the new needed one. Give it a try
I am sorry to say that Topo Norge Premium 06 Hamar - downloaded from the above links - does not show up on my Oregon 550.
Works ok in BaseCamp though...
Anyone who has met the same problem and solved it?
If so - please let me know how you fixed it
The Hamar map works fine in several devices, I personally checked this in GARMIN Dakota, Oregon, Montana and EDGE 800 before posting here.
I think, you are using too many active maps at the same time. Read my post #102 above please, maybe this will help you to see this map on your Oregon device.
There are limits to the amount of maps that a Garmin can handle.
Try this: disable some maps on your SD-card by changing the name from yourmap.img to yourmap.im or something similar.
Now your missing map should show up in the map-list.
This way you also can find out the map-limit for your unit.
Another limitation is the amount of map-tiles in total for all maps: for an Oregon/62s the limitatation is about 4000.
