I just installed my new 898c SI Combo on my trolling motor and loaded the new 6.180 software updates successfully. Next I connected the 898 w/my 997 via the Interlink and it works perfectly. The 898 accepted all of the 997 waypoints...so I figured I'd check out some waypoints on the 898. I scrolled down to waypoints and after the 1st waypoint number, the whole unit powered down. I tried this 2 more times and got the same results. Now I will say I haven't purchased my Lakemaster Wisconsin chips because I'm waiting for version 3 to be released.But I should still be able to go to my stored waypoints on my 898 because it has built in maps. So am I wrong & I need a chip in the unit or is there something wrong with my new 898? So does anyone have any ideas?
