Tuned and Synch'ed
I have a Garmin Nuvi 295w. I want to splice in, connect to the supplied Tom Tom wire (hardwired from factory on motorcycle) that is outputting 5V with 2 wires 1blue, 1 green. The Nuvi mini usb has 1red,1black, 1 white. I have cut off the wire from a 12v nuvi 12v outlet (by passing the resistors since the Guzzi TT is only at 5v Safe for the Nuvi) and tried using the red and black connected to the green, blue from Tom Tom. not using the white. No go I checked with a v meter coming out of the 12v power outlet and the white wire seems to be outputting 5v +- The black nothing and the red? Any suggestions? The Nuvi might have something wired into the 3 wires that tells it to charge while navigating rather than just charge when hooked up to a PC usb. Any Suggestions? I'm not a wiring guru...
