I have my F90BT installed in my wife's car, it is a 2008 Ford Focus, it does have Sync, the issue we're having is with the iPod, it never had a problem in my car but in her car the iPod only stays at one volume and it's loud, any ideas?

So you cannot turn the volume down while iPod is playing or the numbers decrease but the sound level stays high?

The numbers decrease and increase but the volume stays at one level however if I disconnect the Ipod part of the cable, usb works just fine.

When did this happen? Recently do an update?

Not sure I haven't used the IPod in her car and I brought it over for a trip and we ended up not using it because it did this, it's at an awkwardly high volume level.
