[QUOTE="RZ350, post: 755434, member: 13475"] I just read about someone "cracking the code" for automatic re-direct of audio output from the 1/8" Nuvi jack through the 3 connections on the cradle mount whenever the GPS is docked. Supposedly, it a simple matter of connecting Pin 7 (ID) to Pin 8 or 9 (the main grounds) via a 2.2K resistor in the 18 pin connector. The low voltage signal fools the GPS into thinking there is an external device attached and switches the audio output. When I have a free moment, I will give it a try. If it works, I plan to add a switch in this resistor "jumper" so I can choose between piping the music to my helmet, or if I'm parked and just hanging out, have the music output through the built-in GPS speaker. The AquaBox lid needs to be flipped open to hear any audio from the GPS unit anyway, so I will just mount the switch somewhere inside there. I know the built-in speaker doesn't sound that great, but it would be better than nothing. It might also be nice to hear general GPS audio when programming routes and such, with the helmet off. More to come... [/QUOTE]
