The phone cord connection to the V1 to the power source has to reverse the connections from one to the other. It appears that if you don't do this, you fry the V1.

Before I connect power to the V1 mounted in my new roof rail piece with the StreetPilot GPS, I want to be absolutely certain the connections are correct. Since I have a funtional V1 setup in my Civic, but the connections in the S2000 are a labyrinth owing to earlier installs and changes and have been cut on one end, I'm no longer certain whether the phone cord is correctly set up. Can I take pin out voltage measurements from the four phone cord connectors to determin the right pin orientation? If so, what should the reading be when everything is powered up?

 

I believe the power cord is just a regular RJ-11 telephone cord.

I would just take a regular phone cord and do a connectivity test on each pin to get the pinout diagram.

 

Yep. I used regular rj-11 cord when I replaced the cords that came with the V1 -- they were too short!
