Nav system slowdown?

Up until just recently I've really liked the nav system... but last couple days somethings been going on with the voice portion. The lady will be silent when she should be announcing turns. Then in the middle of an open road she'll suddenly announce to "continue on..."

The map itself is correct, just the announcements.

I've done the reset by holding down the power button for a few seconds, no help.

Any other ideas? Were there any over-the-air updates?

 

What software version are you running?

 

Not sure which number: audio: 0101A5, Audio system: 000075B, DSC: 520050, sub: 010001, can: 130209n

Note:There is a screen for "Update history" - which is blank, which would lead me to believe there have been no updates... but I know it did one when I first got the truck.

 

You need to find the screen that shows the software as 3.2 or 2.1, etc.

All those other numbers dont relate to the software version. Go to General Settings---->System Information

 

Here is a pic of the screen:

 

How do I get there? I only saw one place that had ID's and it was the one I listed.
