[s-cars] In Car MP3 Players

[Matt Russell]

Kirby-
Those are great ideas.
Believe FCC doesn't allow anything more than 1 watt, or so I remember from
my college radio days.  But, how do the drive-in movie theaters get away
with it?  I'm referring to those that offer the soundtrack of the movie if
you tune to a certain frequency on your car stereo.  1 watt would be more
than sufficient for the range we're talking about.  Now that I think about
it, some manufacturers offer wireless modulators that must put out some sort
of in-car only signal...

As far as the FM freq, I believe most manufacturers of these modulators give
you only 1 or 2 to choose from.  Is there a way to change that?  Hack in
somehow?

These all sound like a good ideas.  But going back to Thompson's post with
the pic of the back of his radio....

I think you might be able to use the 2 inputs in the changer harness labeled
" Line In L & R" should be where the changers' sound input comes in.  Tap
into those wires, and you should be set.

Note again that I am only guessing that this is where the signal comes in
from the changer.
Anyone have some BTDT on the Bose units?

Linus, any more ideas? I'm thinking that if those are the proper input
wires, all you'd need now is some sort of line-level converted signal from
the mp3/iPod player, and you'd be good to go.  Sorry if some of this is
jumbled.  It's a cool idea, and my mind is going faster than I can type.
