I am looking for the Nuvi 3760LMT cradle pinout (I mean the pinout of the interface between the Nuvi and the cradle, not the 5 pin Mini-USB type B receptacle connector at the device).

It seems that there is an intermittent contact between my Nuvi and the cradle because sometimes the voices and sound is not played thru the speaker mounted at the cradle and I need to lightly tap the Nuvi to temporarily solve the issue.

I expect to be able to repair my Nuvi with this information.
