Thanks for cheking. When you have time will you check 3790 also.
The Application I have in mind is a mute controller. (car kit). (Stereo from Nuvi is not important)
Like Cellphone MP3 or Ipod +Nuvi, When Nuvi Speaks Ipod Shuts Up (automatically), Have to do it by the mount because I need 5volts from the mount to power my electronics.
Also that cable is ok for once or twice usage but not for for everyday usage. Some days I remove nuvi from mount 20 times.
When I have money I will buy another mount to see. But if I can get pinout it will help me, maybe someone has a broken mount ?
