Map Combo Beginners Guide and Secrets for ATS & ETS2 1.58 (2026)
Map Combos for SCS trucking games are not an easy for newcomers. So you can find lot of ready setups for actual version, including here on Trucksim, but before start better to avoid obvious mistakes. In this guide I’m explaining how to build map combo for Euro Truck Simulator 2 (ETS2) or American Truck Simulator (ATS), from how to download and combine maps, to tricks how to avoid crashes. I will cover the basics for beginners. Guide made in 2024 but is still actual in March 2026 on game versions 1.58 and latest DLCs

Merging profiles news
Since I’m merging discovered map sectors in my profiles periodically my old method with Notepad++ is time consuming and I decided to right a script to combine strings and generate list of unique values with proper sequence. Everyone can code today thanks to AI. So I’m planning to make updated guide which can help players with several different profiles and numerous map mods setups. The longest part of it for sure to create media, make a structure and do voiceover, so it will take time. Until that you can use my previous year-old guide which is still actual.
[February 2026] No more 99.99% on Promods 2.81 (1.58)
Quick reminder: for a long time I’m trying to discover Promods for 100% but unfortunately peak score I had is 99.99% and after each map mod update and new SCS expansions, these numbers are decreasing. For instance – I had 99.99% on Promods 2.77 but when Promods 2.80 for ETS 2 1.57 released I got only 88.70%. 2.80 was a big update and brought integration with Nordic Horizon DLC and Scandinavia refresh and new content to the mod. I haven’t combined it with discovered NH DLC areas from different profile (which is 100%).
And after release of 1.58 version (and Promods 2.81) my progress is on 87.86%, so I’m gonna merge it with main vanilla profile and maybe will share it with my Patreon subscribers. And will hit the road of new undiscovered roads. Who know how much time it will take to reach again at least 99.99%. I’m sure you can do it faster.
So below you can grab my progress strings for 2.77 and get those 99.99% and wait for bigger numbers or discover those 12% on your side in Promods 2.81 (or maybe you will reach 100%).
On the video below you can find PM 2.77 on ETS2 1.57 progress and also I’m sharing the link to guide how to merge profiles.

100% discovered study 02.24.2026
With version 1.58 of both games, the situation is a bit different.
In ETS2, we still have 100% map completion, and the guide below remains fully up to date.
However, in ATS, we received a major map update with the Route 66 rework. With the American guide below, you will now reach only about 96% completion out of the box. I’m still running deliveries and haven’t reached 100% yet. Most likely, I will skip this version and won’t create a dedicated guide for it.
The reasons are quite simple: time is very limited on my side, and there’s relatively low audience interest in ATS 100% guides. On top of that, we’re expecting the Illinois DLC this spring.
That said, if I finish my discovery soon and see no signs of ATS 1.59 or a new map expansion by the end of March, I may share the updated strings — at least for Patreon subscribers.
[Guide] ATS 1.57 – 100% Explored map with all DLC (with Louisiana) (December 2026, ATS 1.57, all map DLCs with Louisiana) Actual to 96% on ATS 1.58
[Guide] ETS2 1.57 – 100% Explored map with all DLC (with Nordic Horizons) (January 2026, ETS2 1.57, all map DLCs including Scandinavia Rework and Nordic Horizons DLC) Actual to 100% on ETS2 1.58
I do these discovery since 2017 and I discover whole map almost on every game versions including all expansions and reworks.
Promods 2.81 Released – Guide How to Download and Setup
New Promods 2.81 has just been released. You can enjoy new version on the ETS2 1.58 but note that all map DLC are required. In the guide below as always you will find step by step instruction, but please watch carefully and don’t ask about archives on the Youtube.
Hidden Roads Study – February, 18 2025
Since the last update we have numerous new secret roads in ATS 1 .58 I was thinking about updating the guide for America – I found already 10 new hidden roads and still in progress. But I believe soon we will see also new Illinois DLC so can expect new secrets on that new state. Unfortunately youtube rank and promote older videos first and below guides have a very bad discoverability and low views. So I don’t want to spent a lot of time for guide with 700 views.
Below you find all hidden roads in ATS and ETS2 found in version 1.57.
You can see the complete list of cities with hidden paths here: https://trucksim.top/y9t6. It is probably won’t help you with exact secrets locations but you can check if you missed any.
I’m sharing found hidden secret roads in both American Truck Simulator and Euro Truck Simulator 2 periodically since 2022 when this feature been released on ETS2 and ATS 1.44. But maybe right now it is time to freeze the series and let others do this job.
ETS2 (updated 01.24.2026, actual on 1.57 with Scandinavia Refresh and Nordic Horizon DLC, 110 roads so far)
ATS (updated 12.26.2025, actual on 1.57 with Louisiana DLC, 245 roads so far)
[Guide] How to open 100% map in ATS with all DLC incl. Louisiana
This guide is little outdated if you switched to 1.58, where there are extra roads added but it is still actual and can be used to start with kind of 96%. And for 1.57 with Pelican State (Louisiana) here is whole 100% profile and source file.
Obviously you need all map DLC and as always I would like to remind you to back up before doing anything with your profiles.

Multiplayer Guide for TruckersMP on ETS2 and ATS
The guide created in 2024 but more or less is actual to this date.
I tried to explain basics which can be useful.
Map Combo Study 02.06.2025 (Final for 1.57)
Open Beta 1.58 for both games is available now and I will not update map combo setups for 1.57 unless minor fixes of links will come. With official news about game version 1.58 starting to surface, it’s safe to assume that an open beta is just around the corner. 1.58 is major update so we have to give the modding community some time to adapt to the new features and technical changes and release new vesions of their maps.
Until that happens, we still have large and stable map combos available for both Euro Truck Simulator 2 and American Truck Simulator. Big for US and Giga for Europe.
There are already well-established rules and best practices that help avoid conflicts and common mistakes I’ve covered in Beginner’s Guide, which I strongly recommend watching before building or updating your map combo. It will save you time, prevent recurring issues, and help you create a stable and enjoyable setup from the start.
