I have a TOMTOM 1535 and have tried everthing I can think of to change the default vioce from US English "Smantha" to UK English "Emily" without any luck. The "Emily" voice shows up on the device, but is greyed out.  I've changed the default language both on the device itself, as well as in the My TomTom control panel. I've done a soft reset too.

Any Help?
