Quite aside from Alitnil's suggestion (which _I_ like, but it would change an established feature, which might be a no go) - the Thargoids don't need to be in every corner of the Galaxy. The background mechanics would be complicated, though:
- have Thargoids patrol/explore remote systems, just like we do
- if in system, they can see us as well as we can see them (I hope there's space on the scanner for another set of symbols...)
- an ADS honk (or the equivalent on Thargoid side, let's be fair) would be audible for several ly in every direction, with decreasing amplitude and therefore location accuracy
- based on Thargoid's location and accuracy of detection, some may come to investigate, but may need some time after the honk (for triangulation and of course travelling there)
- the same might be true vice versa, i.e. an ADS detector as a new component that will show if someone/-thing a couple of systems over is using an ADS
- two birds with one stone: if you use the current crude ADS, you'll be audible/detectable ~10 ly over. Use Alitnil's suppressed scanner, and you can only be deteced up to 1 ly away, so basically just in system (where you can be seen anyways). I could even make a good cause for the mechanics behind that, using some handwaving and signal processing, but I'm sure you're not all that interested in e.g. spread spectrum radar and stuff like that

Ahhh... I knew there was a reason why I wanted to have an armed and armoured explorer.
