Thank you, but credit should go to parider as he was the one who originally posted this tweak. The others and I merely improved on it.
I have tried all the options listed here, and none of them have given me the ability to change the voice when using the full menu.
However, it can be changed in EasyMenu (under "Advanced" options). You can temporarily disable the Full menu, change the voice in EasyMenu, and then re-enable the full menu. Changes you make in EasyMenu are carried over to full menu (and vice versa).
I have no idea about coordinate-based navigation in the XL/XXL series though.
thanks for the reply, my apologizes to paride by omission that i did, was inadvertently.
