@Reminder: can you tell me what my character thinks about the map after checking it? I’d like to decide if he will ask for that map Smokescreen offered for a favor.
I'm not exactly sure what you are looking for in reference to seeing on the map, so I can't tell what your character thinks about it. Assume the mapsoft has general terrain info, ground cover, etc. It is clearly sufficient for you to navigate by if that is what you are looking for. Well, unless you glitch, or, better yet,

crit glitch

or something .
Based on what your contact told you, he may have some slight knowledge of the area, but admits himself it's not much. So it's basically if you want to see if his has anything that isn't on the mapsoft version (and I am not going to promise anything he knows will help), then you will need to take him up on his offer. I would have put a price on it, but you had said in your writeup you two didn't know each other well, but had traded some favors, so you will have to decide if you want to owe him or not for what may or may not amount to anything useful.
