Got it in yesterday, put it together last night, and tried it out -

Let me say, I'm inside a metal-frame building, so GPS reception is
a no-go...

So I hooked everything up, and fired both units up in simulator mode.
It let me sync the waypoints and all, showed my weathersense on the
front df, everything seemed to be working fine.

Then it started losing interlink, then regaining it -
and I started to get that old feeling in the pit of my stomach,
trouble.

But got to thinking, and hooked to the boat and pulled it outside, let
it lock onto satellites, and it works fine out there.

So FYI, if your putting on an interlink, don't spaz out till you get it outside
