There is a fairly high probability of precolumbian trade between Mesoamerica and nations living in the modern United States, for which groups such as the Chichimec would act as ferries to bring goods from one side to the other. The most prominent example of the results of a greater pan-American trade is the spread of corn, that is to say maize, to essentially every indigenous agrarian community in the Americas, from Venezuela to Canada. This exchange, however, took place many thousands of years ago. For the more near trade, occurring concurrently to the European Middle Ages, we're looking at a lot more material goods than crops.
The trade from south to north and vice versa carried what important status items, or it could be said that these became important symbols of status because they were largely imported rather than local. A characteristic example of this trade is the flow of obsidian to the north, and pelts to the south. There was also evidently a spread of chocolate, with chocolate remnants being found in bowls from Puebloan nations, while a late Spanish mission in Texas records that chocolate grew on the coast there. For linguistic evidence, the Karankawa word kolame is believed to possibly originate from the Nahuatl word comalli for more or less the same product, indicating that they made have traded for them before learning to produce them on their own.
This is not really a direct interaction, mind you. They mostly acted through intermediaries, in the same way that any goods passing from Rome to China and vice versa would need to be carried by Persians for the middle stages of the trip. So, there is a trade between Mesoamerica and areas within the modern United States, but the Aztecs were not personally carrying the goods, and most certainly they did not produce maps of these distant lands they'd never visited. Of those who were capable of making maps at all, they had their own world to deal with - the states of Mesoamerica would take priority over trying to figure out how far north the angry nomads go. On top of it all, the maps they did produce, if any, might not be entirely what you expect: this is an example of a Mesoamerican map, produced in the early colonial period
To conclude, while there was a trade network ferrying goods form north to south and south to north, little to no direct interaction was properly involved. There weren't really maps of this far north on the Mesoamerican side, and the tribes of the far north wouldn't produce maps at all. While we should never be surprised how far trade networks can stretch, we must always remember the context in which they take place, and the societies guiding them, which overall simply did not produce an environment conducive to a sort of expeditionary exploration as seen in later history.
There's been a few prior answers about trade and communication between Mesoamerica (the cultural region or "Cradle of Civilization" the Aztec, Maya, and many other similar city-based state societies such as the Mixtec, Zapotec, Teotihuacanos, Purepecha, Totonac, etc belonged to) and Native American groups in what's now the US, such as
To summarize, there's pretty well established evidence of trade between Mesoamerica and the Southwest US, with sites in states like Arizona and New Mexico with macaw skeletons, rubber balls, ball courts, cacao, etc. For a long time it was thought that one of the main goods the Mesoamericans were getting in exchange would have been turquoise, but a recent study from 2018 calls that notion into question, finding that many examples of turquoise from Mesoamerican art would have been procured inside Mesoamerica.
