Hey, sorry about the late response.
Thanks for the update about your case, yet another success case!, enjoy your new 3.4.
About the saved locations, I do not have any clue to be honest. I haven’t used the native GPS that much, in fact I’m still running 3.0 (go figure… hahaha)… The only addresses I have loaded are the ones for work and the garage, and that’s it. Maybe a few favs more, but in my case it would take longer to export/import them than just re-adding them.
I do not remember any “export” function on the native GPS on 3.0, but then again, I haven’t hardly used it.
Take care.
