Just make sure you only have one device with the ID resistor otherwise the Nuvi will not recognize what device is connected. Even then, the load on the USB side, since this is the side that needs to be in parallel, may be a bit too much for a good signal out of the Nuvi.
You may need to think about suppling power to the GTRANS cable from a source other than the Nuvi too. The Nuvi can accept upto 500 ma for its own use (battery charging through the data port), but only supplies a limited amount of current (through current limiting circuitry) to external devices even with power connected to the back of the unit. The ideal would be a serial splitter where both TX/RX would go to the T2 and the TX out to a Garmin to NMEA converter for single ended use. New product Scott? The clouds have lifted. Time to go back outside and play photographer on the beach.
