04 CRV (CR-V) RF modulator install?

I'm in the process of purchasing an 04 CRV (CR-V). In my previous
vehicle I had put together a video setup so my child could watch video
tapes in the back seat. This was something I put in for a couple
trips a year and removed otherwise. I'd like to do a better job with
the Honda but still want to keep it simple and be able to remove the
system when not in use.

I'm thinking about this video monitor:

I need to solve the audio feed problem so I thought I'd install this
FM modulator:

The modulator would be a permanent installation with leads exposed
somewhere so I could connect the audio from a VCR or DVD player.

Now the questions:

The FM modulator assume the "standard" antenna input on the head unit.
I don't want to remove the head unit to find it's got some other type
of antenna connection. Has anyone else pulled their head unit and can
verify that it has this "standard" antenna connection?

The modulator needs power - at least when the head unit is powered.
Is there a source for information on the power to or from the head
unit somewhere that I can use to do this right? I can play the game
with a meter and a needle to probe around but would prefer not to.

Forget FM modulation, get a PIE or Blitzsafe adapter for cleanliness and the
best audio quality.

Great site! I think the problem is that I'm buying an 04 CRV EX and
it comes with a 6-disc changer, which consumes the port these things
take advantage of.

That shouldn't be a problem either. Most if not all integrated
installations come with a two port harness that allows you to insert the new
device into the loop without losing any functionality already installed.
