On a Nexus 5 doing the first doesn't change anything for me; it's just less accurate (I did so, then opened up Google Maps to double check).

But you're going to have to define what you mean by "Google code", because ostensibly all of Android is "Google code". Doing what I outlined above will stop it from going through any form of sensor fusion. If you want to remove Google's service software then just create a build without Play Services on it, it's that simple. AOSP boots, on the Nexus devices at least, without it, so it's easy to do and gets you exactly what you want.

So really I guess I'm saying: What else do you want? Remove Play Services, the Google Apps, etc, using an AOSP based build and you get a Google free phone.
