Works as advertised! Be sure to upgrade your Nuvi 350's firmware if your at version 3.2. I bought an eBay special for $31.00 shipped, but couldn't get the cable to work at all. My D710's GPS icon wouldn't flash so I knew it wasn't talking to the Nuvi. After upgrading the firmware from 3.2 to 6.2, I plugged in the Gtrans cable and my Nuvi displayed a message regarding not supporting serial devices on battery power (or something to that effect). I knew The firmware was the root cause after seeing that and needless to say it's worked flawlessly since!
