    Audio panel or stand alone intercom

    Here's the dilemma I'm wrestling with.

    Minnie's current avionics are as follows:

    The "center" stack consists of from top to bottom

    KLN-90B (recently installed)
    MX-170B #1 nav/com
    KX-170A #2 nav/com (old 360 channel that will probably be replaced with an
    MX-170C some day)
    Narco AT 50A transponder (yeah, that's pretty antique too)

    To the left of that top to bottom is
    KR-22 stand alone marker beacon receiver
    KI-214 VOR/LOC/GS indicator (with integral GS receiver) [will have to be
    replaced with something that will work with the GPS for IFR cert]
    KI-203 VOR indicator
    "audio panel" which is nothing more than 4 individual toggle switches to
    select which com transmits and whether #1nav/com, #2 nav/com and mkr
    beacon go to phones or speaker.

    Here's the rub.

    I had envisioned that one day I'd put in an audio panel with an integral
    marker beacon receiver and intercom.

    I THOUGHT that would fit at the top of the stack. Well it won't so it
    will have to go to the co-pilot side and either over or in place of the
    "glove box."

    Well I already have a separate marker beacon receiver and it's over the
    indicators. If I put in an audio panel over to the right, the marker
    beacon lights are way over to the right, i.e. not within instrument scan.

    So I could go with an audio panel w/o the marker beacon receiver but w/ an
    intercom.

    SOOOOOOOOOO the question is: is it worth it to install an audio panel to
    get rid of the four toggle switches that functionally work fine and
    combine that with an intercom or just stay with the toggle switches and
    just install a stand alone intercom. That would probably be about $400 +
    $1,000 to install. The audio panel would be a little more expensive to
    buy, not sure how much more the install would run.

    Any thoughts?

    Audio panel or stand alone intercom

    I did a GNC300XL install which required an external annunciator with a
    new/used GMA340 - I put the annunciator at the top of the stack which
    took about an inch and that moved my GMA340 low enough for it to fit and
    clear things. I ended up putting in a GTX327 transponder at the same
    time (my KT78's goose was cooked).

    Here's some thoughts...in your case I'd invest in a new audio
    panel/intercom/MB receiver - if you add a real intercom you'll have to
    touch just about most of the audio wires in the system anyway and I find
    that a nice integrated panel although a little gee whiz _is_ nice. Does
    the KLN90B require external annunciators for it's install? If it does
    leave space for that at the top of the "center" stack and drop the audio
    panel a bit and then it all should fit. You'll reclaim a lot of panel
    space versus the current setup.

    If your center stack is looking a little tight vertically you can
    reclaim 1-2" if you replace that 170 with shorter nav/com like a 12D+,
    KX155/125/165 or even a 1" like an SL30/40 (these are surprisingly cheap
    on the used market right now).

    Also it may make sense to replace the Nav/Com and the CDI at the same
    time - you should be able to pick a pair that will pay well togather.
    If you do this you might want to leave the 214 alone and replace the 204
    instead given the KLN90B doesn't do LPV or VNAV (I think) - you can use
    a slightly cheaper GSless CDI - or if finding good used deals the
    incremental cost of GS is pretty small usually so you could have a
    backup ILS setup as well - then the CDI wouldn't need to be replaced if
    you upgrade the 90B to something later that does LPV/VNAV.

    But the real net is Given the 170A is due to be replaced and you need a
    new CDI with a resolver for the 90B - I'd leave the 170B/214 combo as is
    and replace the 204/170A at the same time.

    BTW - you should be able to find a used GMA340 or PS7000/8000 level
    panel/intercom in the $800 range...and if you're already wired for 4
    places the wiring for the intercom should be somewhat less than
    $500...and I really wouldn't expect a big delta - you've got to touch
    the wires for all the intercom spots and later for the 170A replacement
    - so tackle it all now. Also if you're leaving the 170A in for now let
    the avionics guy know replacement is on the list and he can leave a
    extra loop of wire or hookup via a 2nd molex connector to make it easy
    to pull and wire in the new nav/com later.

    Audio panel or stand alone intercom

    I had a not disimmilar situation in my little sport.

    Went for the cheapest panel I found - The Garmin 340! Fell into place,
    cheap to install as everything hooked up fine, brilliant clear audio and
    we brought out line to allow kids to plug music players in and get music
    enroute too. Also all sorts of strange crackles dissappeared as the
    number of wires and connections reduced. Go the panel.
