Hey thanks for all the reply's to clarify my sonar men can "hear" the contacts fine if i tell him to report the nearest etc but when I go there and try to hear it myself even if i am very close to them I hear nothing and the green light comes on sometimes to let me know that it is picking up something, which led me to believe i had inadvertently deleted some sound files, I am not aware of doing that as its a fairly simple process however the sounds aren't there so maybe I have, I have dried going a bit deeper to but no luck.
I can hear contacts sometimes though, but other times I can't even when I should be able to.
