camcorder recording Cessna intercom audio question

Two choices...

1. Instead of going to the "mic in" jack on the Sony, go to the
"line in" jack if there is one... or ...

2. Run a 100kohm resistor in series with the line between the phones jack and
the mic in jack with a 10kohm resistor to ground from the mic in jack. If it is
still too loud, diddle (that's a term for heuristic engineering) with the 10k
resistor down in value until it comes out clear.

-Help!
-
-I tried recording the Nav/Com audio to my Sony camcorder in a c172. The gain
-is so high it just sounds like saturated noise. I basically wired from the
-co-pilot's headset jack a cable to the sony 'mic in' jack. Has anyone here
-successfully recorded a flight with clean audio, and if so, how ?
