I have a question concerning setting the time and date on this locater. I know how to change the size of the letters and numbers, using the overlay data menu, but can't find how to set the current time and date. When I turn the unit on, the time shows 12:00am and the date is wrong. Read the owners manual and it shows nothing on how to do this. Strange. Maybe I should call Lowrance and find out. Any help would be greatly appreciated. Owners of this locater have the same trouble? Thanks.. Mark.. ps. I will check the posts at a later time, because I will be leaving for Memorial weekend tomorrow. Be back on Monday to check replies if any.
