google maps + gps not updating location

[holo]

I have been running google maps with my bt gps for a while now, but one thing I have noticed is that it completely refuses (99% of the time) to update the location from the gps without me manually turning 'track location' off and back on...

This worked for me one time when I first got the gps, I was driving home and watched the blue dot move almost the entire way but then it stopped near the end... I figured this was because I zoomed in too far (?) but I have tried to get it to do live tracking again and have been completely unable to replicate this, trying to zoom out/etc....

Am I missing something here? Is there a setting or a workaround to get it to actually follow me? It's very annoying to have to disable and reenable it every time I want to see my new location....
