Well that worked!!! I was able to copy and paste it right over the orig. after renaming your course file exactly the same as the original!! So now I will have to try this out now in a noisy envirment to give it the true test. Seems like it is louder now but not sure yet? I will post when I am indeed for sure this worked incase another alltel user runs into the same problem. I realy do appreciate your time and knowledge thanks!! This is the only issue i have with my pda if this helps i will never get rid of this device!!! I have talked to so many different people at alltel about this and not one of them has a clue or has heard of anything!! Just floors me that not one person in the us has complained about the incall volume to alltel!!! You literally could never hear anything!!!
