well, i did the 3.0 and everything worked flawlessly, then i "upgraded" to the 3.01 and somehow lost my nav voices and key beeps, unless i am listening to the usb. If i listen to the usb then everything works fine, but as soon as I switch to cd, sirrius, or tuner i loose the beeps and voice. Any suggestions?

Have you found a fix for this yet? I have the same problem after I did the upgrade.
