Route numbers

On ibis, how do I know what route number to put in? I tried reading the manual etc but get False route everytime.

Enter the line first (e.g. 09200) then the route (e.g. 1), and the destination will set automatically, then you should be able to see the terminus on your screen. Drive to the next bus stop and press TAB/Q and it should read the correct stop.

Hmm, odd. I do that, line 09200 and route 1. (starting at fru) but it still comes up with false route. Yet if I do it on an ai bus it works. So im selecting the wrong route or something? Gah confused.

Wrong depot?
