No telling why my GPS Info is different from yours but it is. No doubt my firmware is outdated due to the 6-7 year age of my BU 353. It seems like updating firmware is not user friendly so I will keep what I have. Hopefully changing transmit/receive speed to 1 will do the trick. If not I will concede defeat. My July 27,12 dated drive must me up to date. Thanks for your help.
