I read the Posts below about the 6.180 updates and they all have to do with sharing way points and using a eathernet connection between two units. I am just using a single 898cSI unit. I have the 5.410 update on it now and was going to update it with the 6.180 right now but after reading the problems people are having I am not sure if I should do it now or wait till all the bugs are out of it. My unit works fine and I hate to cause a problem but really want that update. This will be my third season using it and have logged 706 hours on it and really love it. Just wanted the Pro's here opinion on this topic for a single unit. Thanks for any help or suggestions. Joe
