I am on the stock ROM, just rooted. Correct I do not turn GPS on or off with a flow. GPS is not available to Maps unless I manually turn it off and back on. The it operates normally with proper accuracy. If I exit Maps and then re-open it I have to manually toggle GPS again before it works.

That is correct. On the Galaxy S4 you can leave the GPS turned on but it doesn't actually activate or show the GPS icon in the status bar until an app like Maps opens. With the GPS trigger enabled the GPS icon doesn't start when Maps is opened.

If I set Periodic Location Update to Network other apps like Car Dock and Google Maps can activate GPS automatically as normal. If I set Periodic Location Update to GPS other apps like Car Dock and Google Maps no longer activate GPS automatically.
