I am sure the brain trust here can help. I have PP on an 2004 boat. It is the version that came with the boat. Not stargazer. If I change the battery (it is getting weak because of it's age), will I lose all of my PerfectPass settings? If so, is there a way to prevent this from happening? I really do not want to re-program it. I'd check the manual, but I have no idea where it is located.
