It seems it does not
Kerrect, assuming you're not interested in APRS. I love mine, but if I didn't do APRS there is no way I would have bought it.
The GPS can be used through the radio on a computer, but it will do EITHER GPS OR data... not both at the same time. The radio does have a built-in navigation system, but it reminds me of early attempts to do such things (clunky, text and bad graphics for the readout, etc). From a navigation point of view it isn't a great setup.
Now from a HAMgeek perspective it has many features and interface improvements over the other Yaesu models, including that big beautiful display with crisp, easy to read text/icons. It also has a built-in mic and stereo speakers, which is nice if you don't feel like picking up the mic or have more than one person in the conversation in your vehicle... audio performance is good. Memories are easier as well IMO, since the added screen space allows you to see both your memory name and the frequency at the same time on both sides of the radio. The menuing is easy to navigate and intuitive... I've had no trouble quickly getting to the setting I need even on the road.
The APRS features are very easy to use thanks to all the screen real-estate available. It is also arguably cheaper to go this route versus Kenwood + external GPS or another radio + GPS + TNC (I paid $650 out the door). I have a hard time picturing a cleaner install than an all-in-one unit like the 350, which might be important depending on your options for installation.
I'm somewhat new to the world of amateur radio, but if you have any questions about the 350 feel free to ask and I'll do my best to answer them.
