I've got an 8000 and installed the firmware update with no problems. Everything seemed to work just fine until I used turn by turn guidance in Maps. The voice prompt is LOUD and I mean LOUD like the speakers might blow. At first I thought this was just me having the setting in the Maps app on the phone set to high. However, the setting was set to low. I decided to change the settings and retry and none of them seem to have any effect. No matter what I do, I can't get the guidance voice to a "normal" volume. Has anyone else had this issue?
