Just bought an xi5 and first time I tried the anchor the gps light came on but it would not hold it’s position. Since then the gps light doesn’t even come on. Motorguide says the gps module is bad but I can’t get it worked on because the boat store where I bought it isn’t a certified dealer. So now I have to take it somewhere else because Motorguide refuses to even send the parts to my boat store. What a piece of junk. Don’t make the mistake I did, buy something else.
