Only recently started using Navigator and Maps again, and now, I get this annoying "beeping" sound periodically. It sound much like the audible tone you get when you touch the phone. I found no settings in Navigator or Maps that deals with this in any way. Also, I'm using the phone in an iBolt car dock and it launches CarHome Ultra when connected. That has an option to notify on location changes (City Alerts) -- which is set to "none". I've only noticed this since the recent round of Maps and Navigator updates. Anyone know what to look for to disable this annoying sound?
