I have a Galaxy S3 with a Lexar 32Gb class 10 micro sd card and started having the unmount error issue today. This is after using the card perfectly fine for over six months! What gives?
Yeah, that's right. For me, it would switch between the male voice and a non-robotic female voice. Now it's just the robotic female voice and no street names, just "turn right" or "turn left" which isn't very useful.
Thanks for the suggestion/reply. I've tried all that and still don't get the street names called out as before. Ah well... I guess I won't be using Navigation until it's resolved with a future update.
I had the same issue as well. Thought I going crazy. I'll try un-installing the update as you have all suggested. I hope it works.
Just tried it to no avail. I still don't get the street names called out as before. I don't know what to do... :'(
