After discovering this great forum I tried to change the dog-sound warning for speedcams. Tried to add it in the directy structure and made a new data.zip file as well. The first method didn't work, still a barking sound while approaching a speedcam (and there a loads of them here in the Netherlands). The second option made my european (v1.9) f700bt never get out of the startup procedure (waited for 5 minutes).
Has anyone else managed to change the warning sound on an european unit?
