The Simrad NSS Evo2 is a powerful tool that is mostly used as a fish finder.

This device helps in checking the water current you are traveling on as well as a lot more information regarding the body of water.

This includes checking if any fish are traveling near you and even having a navigation system that is powered using satellites.

The cordless tool has a powerful battery on it that can easily last you an entire day without requiring a recharge.

Though, you should note that the tool also gets frequent updates that add new features to it. Some people have trouble trying to update their tablets which is why we will be using this article to help you out. 

Going through the information provided below should help you in understanding how to update the Simrad NSS Evo2 with an SD card.

Make sure that you go through it carefully to avoid further issues with your fish finder.

How To Update Simrad NSS Evo2 With SD Card?

Updating the Simrad NSS Evo2 is a simple task that takes a few minutes as long as you have a stable internet connection at your home.

However, if you want to install the updates with an SD card then there are some additional steps that you need to go through. 

With that being said, here is a small guide that can be followed to complete the task while ensuring that you don’t get further problems.

  1. Start by finding an SD card that has at least 8 GB of memory on it. The update is usually much smaller, but it is still better that you stay on the safe side.
  2. You can now visit the official website for Simrad to download the update for your device. The website should ask you about the exact model number of your fish finder.
  3. Enter Simrad NSS Evo2 here and then download the latest update that has come out. Make sure that you install a stable version instead of a beta version as these can have some issues on them.
  4. Now proceed to locate the update file on your computer and then move it inside the SD card. If your PC does not support installing SD cards, then you can use an adapter that lets you do this.
  5. Once the update file has been copied inside the SD card, remove it, and then install it inside your Simrad NSS Evo2. The tool should usually detect the card on its own and ask you to open it.
  6. If this does not happen then you can manually open the SD card by accessing the storage settings on your tool. Browsing through the settings is the best way to locate your SD card.
  7. You can now open your card and then start installing the update file by clicking on it. The tool might ask you for confirmation, pressing “yes” should begin the installation after which waiting patiently is the best option.
  8. Once the update is installed, the tablet should reboot on its own and you should be able to start using the new update without any issues.

As long as there are no issues with the SD card and the port is in good shape, you won’t have to go through any challenges.

The update will follow through pretty smoothly, and you should test out the update with a different SD card if the current one doesn’t work. 

The majority of complaints that are listed by the experts relate more with the hardware issues that can present themselves in the SD card.

If you’re also struggling with these hardware issues, the best thing that you can do is to test out a new one. 

There is no point in trying to format and reformat the same SD card and you gotta stick with a new one.

Otherwise, you will simply remain stuck in these errors without getting through with the update. So, when the update is stuck, or the file won’t present itself, just get a different SD card. 

This time around, it would be better if you can get an SD card from better brands like SanDisk. Otherwise, you might just be setting yourself up for failure, and the update won’t go through.

Update File Not Registering With The SD Card?

The most common concern that most people bring up is that the update file won’t register with the SD card.


Either the issue is with the slot or the card. While we still can’t rule out the possibility of issues with the file itself, you should start by figuring out the problems with the card or the port first.

The first thing that you gotta do here is to check the card. Most anglers said that they were able to get ahead of this issue by using either a Sony 32 GB SD card or the Samsung SD card.

There were some anglers that mentioned decent enough results with the Kingston cards as well.

So, if you’re not on these brands and using some cheaper option, then now might be a good time to switch.

You gotta look for a card that is brand new and from a reliable dealer. From there, you can format the card once on your PC, and then move the update file.

Hopefully, this time around, the port will pick up the card and the update file will register properly in the Simard system. Usually, the problem is not that serious and you have a decent chance of fixing these errors. 


Everything boils down to how you’re planning on sorting out these issues. After changing the SD card, you can also check the port for problems.

We all know that the fishing conditions can get rough from time to time. So, you will have to be more mindful of the system’s maintenance. 

You have to make sure that nothing is lodged inside the port and it is pretty clean. Simply blasting the unit with compressed air is usually enough to help you out.

The compressed air will drive out all the gunk and you will be able to access the update file relatively easily.

Next, you might just have to check the file. It is always possible that the file that you’ve downloaded wasn’t downloaded properly.

If that is the case, you will have to download everything from scratch and there aren’t any other options left for you. 

Everything boils down to whether or not the Simrad system can read the file. If there are formatting issues or some other complications with the system, you will remain stuck in these errors.

So, when you can’t seem to transfer the file or the SD card is presenting problems, just replace the card.


On a last note, it is entirely possible that the issue is more with the programming of the Simard unit.

While the chances for this issue are pretty slim, that doesn’t mean that you won’t have to ever worry about these problems. 

If that is the case, you will have to reset the system. Sadly, there aren’t that many options left for you when the issue is with the programming of your system.

So, be sure to have that in mind and reset the system back to factory settings.

We understand that it will wipe away all the configurations and you will have to start from scratch.

However, you’re not left with many options at this point, and starting from scratch is not that bad of an idea when you can’t seem to update the Simrad Nss Evo2 with an SD card. 

Sticking with an outdated system will only serve you for so long. You will have to ultimately switch to a different option and rely on a new piece when you’re stuck in these errors.


Otherwise, you will just be complicating the situation for yourself, and the performance will keep deteriorating.

The Takeaway

Managing the Simrad NSS Evo2 update with an SD card is not the easiest task and you will have to hassle a fair bit here and there to get through with the installation.

There are a ton of issues that can present themselves down the road like the SD card format, issues with the port, and the programming itself. 

You will have to tackle all of these issues and then input the update file with the SD card to get the update through.

The most effective thing that you can do is to stick with a more reliable brand like Sony and Samsung when choosing the SD card.

From there, you can also clean up the port and add the SD card to the Simrad system.

This step should be enough to have you sorted out and you will not have to worry about any extensive challenges down the road.

Hopefully, you will not have to go through too much trouble when it comes to updating the Simrad NSS Evo2.

However, you can still rely on the official support team to help you out when you’re stuck in this problem and can’t see a way out.
