By car
The "Neue Messe München" is right off the A 94 highway. The exhibition site itself recommends entering "An der Point" in your navigational system. Other possible search criteria could be "Ausstellungsgelände" ("exhibition grounds"), "Messezentrum" ("exhibition center") or "Messe" ("trade show"). The "Messe München" website can provide further travel instructions and addresses for various parking garages.
By public transport
If you are arriving at Munich's central train station, you can rent a car from there or take the subway (U-Bahn), line U2, directly to the trade show.
