You could have a couple of different problems here.

That's what I figured...

Have you made the comm connection live on the GPS by selecting Comm port
1 or 2? Is there a similar selection on the radio?

well; no; I've connected by nema in/out

VHF NEMA OUT ---- GPS NEMA IN
VHF NEMA IN ---- GPS NEMA OUT
VHF GROUND - GPS GROUND

Check the wiring connections and make sure that you have NEMA out to out
and in to in. That's a common problem.

Wow -- then I totally fubar'd that installation -- since I read the manual; it
seems like "DATA OUT" form one device goes to "DATA IN" on teh other device....

I'll try it your way. Except the VHF radio is getting GPS data just fine, so
I'm betting that it'd fubar that up....

And you would exactly right.

D'Oh!!!

You have it right.
