My KLN-89/B has a NEAREST function and one of the sub-functions is CTR.
Push that and it knows what center freq to give you. I find that nice. I
also get FSS, etc.

A follow-up to this:

So let's say I'm flying out somewhere (VFR) and I decide I want VFR
FF. Most of the C-172Ss I have flown in have the NRST on the GPS. So
I push NRST and I choose 'CTR'. So this gives me the center
frequency. All good and fine, but what if I am close to the radar
(TRACON) service area of a Class C and actually the airspace I am in
is the domain of that TRACON? I assume that the TRACON area of
responsibility is a little further out than the B/C rings, and then
there are some Approach controls who are not associated with a Class
B/C airport either - Dover and Patuxent come to mind the quickest to
me. So I don't really know *what* the coverage area of Patuxent
Approach is, and when (if ever) it switches to DC Center before going
to Norfolk Approach, for example.

I am assuming the 'worst that could happen' is that I call Center and
they say 'no, dummy, you want to call XXX approach on YYY'. My
question is - is there any way to find out this information
beforehand?

Thanks,
