Yes, it's ridiculous.
Does anyone know how to customize or change the Navman audio alerts?
I played around with a trackmate GPS device, and it's a piace of cake to change and upload your own audio alert and you can use that generically for example with red light cameras. My only complaint about the trackmate is that the navigation voice assistant is not as clear or as loud as the Navmans, and the Navman is much more user friendly.
But I wish we could upload our own F20 audio alerts!
