Does anyone know where I can get a earphones - similar to the ones shown - that would fit a Street Pilot 3? Surprisingly, when in the car I pay more attention to the voice prompts (via the external speaker) than the screen - but the voice prompts have not been available to me while on the bike. I borrowed these off the kids walkman, but the jack connection is too big to fit into the socket on the GPS unit. I'm sure I've seen a thread on here somewhere - but can't find it. Any suggestions would be much appreciated.
