The puzzle’s title is the German word for steamroller, and alongside the mention of Fresh Aire in the flavortext is meant to clue the band Mannheim Steamroller.

In the town of Mannheim, Germany, there is an area called the Quadrate (also alluded to in the flavortext) where there are no street names. Rather, each block is identified by a coordinate letter and number (A1, A2, B1, etc.).

Clue answers can be paired as transadditions (UMPS/STUMP, RELAY/PLAYER, etc.). The flavortext also includes a transaddition (SUITE/CUTIES) along with the coordinate C1, meant to indicate that an C has been added in the first position.

Each pair of answers thus indicates a letter/number coordinate:

Highlighting those coordinates onto a map of Mannheim (included below) reveals they are all contained within a 6×6 subsection of the map.

1. Some maps, including Google, list this as I. The German Wikipedia map, among others, uses J.
2. G1 is also known as Marktplatz on some maps.
3. O1 is also known as Paradeplatz on some maps.
