Weird audio issue on 590lm

[Kevhunts]

So I fired up my 590lm, was paired with my Sena SMH5 head set and set off down the road.
I quickly realized I was not hearing any sounds or verbiage from my zumo despite the unit stating I was paired with my head set.
I check volume settings and everything else I could think of including rebooting and pairing again. I selected a stored route but, still No joy.

Suddenly, the zumo starts blurting out multiple messages and directions. There had to be 8 to 10 messages in succession and finally the most current instruction which matched with the visual display.

Has anyone experienced an issue like this?

Yep, had the same problem several times (as have a few others).
