Day 3 | Maps lost, Kleinbuses found

Second leg done, or first, if we don't count the transportation from Vaasa to Helsinki. Avoided highways and big cities, but in the afternoon I drove some one digit highways, just to arrive a bit earlier, because I have promised myself a things, which I will reveal later.
In Glückstadt I stumbled upon a fire rescue gathering, with incredible 8 old Kleinbuses, as emergency vehicles.
I have some kind of problems with the audio, and I now know the fault, but I don't know if it is a flaw in my GoPro Media Module, or if it is a feature. When I filmed the Kleinbuses, I removed the GoPro with the mod from the helmet, I thought that there has of course has to be a fallback, that it uses the mod microphone. No, it didn't, I have no audio of the boxers. Strangely enough, when the battery gets low or/and if it hibernates, it shuts off the mod, and it doesn't wake up if I don't reboot the camera itself. When it has shut itself, then there's a fallback, the lousy internal GoPro microphone. Can't say I'm very pleased after all the money and effort I put into these GoPros....
