I actually tried that, it's kind of hacky and is not well integrated with google maps or android. Also, if your phone is off or the screen is locked for a few minutes it doesn't work.
I'm not sure how the could integrate it more (or even less) with Maps or Android or what the phone being off or locked has got to do with it. It syncs the same way all Google services do. I suppose it may be working less well on an older or oddly (manufacturer) customized device.
