Thanks Andrey for the reply.
I deleted the reference to speedcam in the sys.text and it made no difference. Where would I find if the voice dictionary contains the necessary lines about the speed limit?
I definitely have all the settings in the skin warning settings set for "warn when speeding", "Audio and Visual" "Warning Type" Voice and Sound", "Beep if overspeed" "1 bip", (this works), "Speed color if over speed" "On", (this works) I get verbal notification of speed limit changes as well.
Is there supposed to be something is the sys.txt regarding verbal warning of overspeed?
