Keith, I would try connecting the GTRANS cable to a usb port but none of my
four computers has a miniusb port not do I have a mini to regular usb
interface connector. I will look for one. Sam

Unless you have done modifications to the Nuvi 350, there is only one USB
connector. The one on the back may look like the same style of connector,
but it is for power only. Users of the Nuvi 350 / Tracker 2 (OT2m, T2-135,
T2-301) sometimes modify the Nuvi 350 to extend the serial transmit and
receive data from the connector on the right side of the 350 to unused pins
on the rear connector for a "one cable" solution. Unless this has been done,
the rear connector is for power only.

Did you ever try connecting the GTRANS cable to a terminal program to see
what if anything it was outputting? The Nuvi would have to be powered via
the cradle... i.e. the rear connector. If you think that you have a cable
problem, I would suggest contacting Scott N1VG at Argent Data.

You mentioned before that received position reports were being sent as
waypoints to the Nuvi. It is possible that data is flowing in one direction.
Connecting the GTRANS cable to a terminal program will prove whether or not
you are getting any NMEA data from the Nuvi. As I mentioned before, the Nuvi
would have to be powered via the cradle or the GTRANS cable won't get power
from the Nuvi.
