Recieved my exchange 898si today in only 3 days! Connected it up and a whole new world appeared! Thanks to HB cust.serv., Eddie @ Humminbird,Bobcat and all the rest who have offered their assistance w/the prob. I had. Cant wait till I can get to lake tommorrow to see it in action. This new "898si" ranks right up there with my first bicycle!

AWESOME! I am real happy for you. I know what that feels like to get something brand new that does not work. That is why I am using Humminbird in the first place. Report back after you use it. I may be asking you questions since you have read the manual a couple of times now.
