There were apparently some issues with that version (the "My Location" label never clearing out of the way was one big complaint I've seen). Google pulled it and went back to 4.4. A lot of people supposedly did that on their own even before that.
I didn't use "my location" because I don't have GPS. And location by cell tower is pretty useless in a city where it could place me anywhere from two streets over to several whole neighborhoods (up to a quarter mile) away from where I really am.
But it was a bit unstable so even I recently downgraded back to 4.4.

Does anyone have an updated link for Google Maps 4.5.1? The above link doesn't work. I recently upgraded to 4.5.2 but it doesn't work on wifi only as 4.5.1 used to.
