Don’t see 24k map displayed in Oregon 750
New here hi
Have a new Oregon 750 and just getting to know it. Bought a used tested 24k Topo on micro SD and installed it correctly. It appears in maps list but when I choose map Screen I only get low grade basemap can’t seem to display the topos. Can anyone tell me what is wrong?
Thanks

If it was bought from Garmin the map is locked to the card, if it's a download it will be locked to the original device.
Asked seller if I can return and ordering a NEW card seems like best bet.
I’m quite the novice on gps units ( Which is why I joined this forum) and expect to have other questions so I appreciate all the help I can get.
I like to roam the woods with my metal detector seeking colonial homesites but Need the security of a good gps to alleviate the fear of getting lost. I had a foretrex but wanted more features and accuracy.
Not having a Mac or a PC is going to limit your capabilities however. There are many free maps available for Garmin devices from sites like gpsfiledepot but unfortunately, most of them require Garmin's software for installation on the GPS. I make maps too, but I also offer them as files that can be dragged right to the GPS so users can install them without a Mac or PC. Unfortunately, there are not many other authors of free maps who offer such an option.
I'd only purchase an SDcard map directly from Garmin or one of the vendors that has been around for many years and also sells other Garmin products.
I have not looked recently, so someone else will have to say if it's changed. Directly through Garmin or it's licensed vendors, you can get a card with the map on it locked to the card and will work in other of your Garmin devices, or you can download from Garmin to your own SDcard and it will be locked to one particular device.
eBay in my opinion has been the worst at getting counterfeit vendors under control. Amazon and a few others better, but certainly not perfect.
The micro SD I got is from an authorized garmin dealer and will work- they say it is a pre-programmed data card and does not need to be unlocked and after unpacking ( I’m taking this as unwrapping?) can be used on multiple devices but not on computer. So I’m expecting it is as simple as inset the card and done
I’m considering getting a windows based laptop to use for basecamp and mapping, but not immediately
Was yours (supposedly) a new product, or something used? If new, then it should have been in Garmin packaging. And all you would need to do is insert it in the GPS. Yes, it's true that there have been a lot of counterfeit Garmin SD cards in the past. I think these were mostly City Navigator maps however.
And yes, the pre-loaded cards will work on any Garmin GPS however they cannot be duplicated (they use hardware-based copy protection that locks the map to the original card). And it's also correct that the downloaded maps will only work on the original GPS for which they were purchased. One advantage of the download product is that you can use it immediately, but there are a couple other less obvious advantages. First, if you lose your original map somehow, it can be downloaded again for free for 12 months (IIRC) after purchase. But IMO the biggest advantage is that you can install the map in internal memory on the GPS if you like, or you can put it on another big memory card along with other maps.
With the pre-loaded cards, you should not add any other maps or data to the card as you risk corrupting it (and there usually isn't much free space anyway). This is a big limitation and you might not understand all the implications. For example, your new GPS can use Birdseye aerial imagery (it may have even included a free subscription). These are very big files that you would typically want to put on a card instead of internal memory. However, if you have a map on a Garmin card then you are out of luck. You would have to physically remove the Garmin card and replace it with your own card of Birdseye imagery.
Unless you have some definite plans to use a map on more than one GPS, IMO the downloaded map is a better choice because it gives you freedom to install wherever you like.
BTW, Garmin used to have a third option of purchasing maps on DVD. This was discontinued a number of years ago. Too bad, because these maps were permanently installed on your computer for use in Basecamp and Mapsource. You could then choose as little or as much of the map to send to your GPS. With the new downloadable maps, it's "all or nothing". You can't just install one or two states from a topo map, you have to use the entire map.
So Garmin no longer sells maps to directly install on your computer. However, you can still use them on the computer by connecting the GPS. Or you could just put the memory card into a slot on your computer (or a USB card reader). In fact, you could even make a duplicate copy of the memory card - the copy protection is not enforced by Basecamp on your computer, it only affects the map when used on the GPS itself.
Thanks for adding that.
If you are using a Mac, you can use Disk Utility to create an empty disk image, then you can copy the contents of a card (or internal GPS memory) to the image. Basecamp will see that just as though it was a physical card.
There is no built-in software to do the same thing on Windows, however you can use a RAM disk, I have done this with an free program and it worked. On either the Mac or Windows, this is different from Garmin's old system, you are basically just creating a virtual SD card which you need to manually mount and eject.
