Please,somebody send me a tutorial on the subject of downloading updates. My unit 898si is in Fl. and Im up here in NY state. Now when I go back down to Fl. Im going to have to update my unit, and have no idea on what to do. I never hpdated anything on the H/B. Now, I bought two s/d Ex 3 -4gb cards. I do know where they go. and thats about it. I also have a 788 di coming this week for the bow,t/m mount. Any help would be greatly appreciated.( And don't tell me where to stick thoes cards !!!) Thank-you much.------- Maineak.
