Just bought a 2010 boat with a 798si unit.Headed to Rainy Lake in 3 1/2 weeks.What chip would you guys recommend.Keeping in mind I am E-challanged.Looking to use basic features to start.Was just starting to figure out my Lowrance unit in my old boat.Thanks Steve Also being almost two years old does it need updates.If so what am I missing without them?
