About two month ago, I reported here (and to Garmin) a problem with
the NMEA interface with my new GpsMap 276C and my autopilot AH/ST4000
and until today, this problem was not fixed by Garmin. I do not
believe that I am the sole user in the world witch have interfaced my
gps with my autopilot, but nobody else reported here this problem:
why?

The fact is that, here I have many friends, witch have theirs Garmin
gps interfaced with theirs autopilots, and many of them have the
problem, and a few others have not, as I showed in my report; In
general, old Autohelm autopilots like AH/ST 2000/4000/6000/7000, have
this problem with Gamins gps models: 130/12XL/45 with NMEA 2.0, III
Plus, III, V, 60C, 76C, and 276C. The problem does not exist with gps
models: 176, 176C, Map76, 130/12XL/45 with NMEA 1.5.

As I had explained in my report, I discovered, after several tests
that the problem is caused by the RMB message, and all gps witch sends
BWC, XTE and VTG does not have the problem, but all Garmin gps witch
does not send this messages causes the problem with that old
autopilots.

As the manual of GpsMap 276C states in page 90, "Advanced NMEA Setup",
that the unit ALWAYS sends the BWC, XTE and VTG, I have the right to
expect that Garmin will fix this fault ASAP, witch does not happened
until now (more than 60 days).

As several users of this gps forum had talked, maybe someone who read
this message could be a Garmin dealer or Garmin employed and perhaps
he/she can give me a help in convincing Garmin to solve this problem,
so that I could use my new and expensive Gps with my Autopilot, as
now I am forced to use again my old Map130 and Map76 for the
interface and keep my new Map276C in the box (since september/2004).

I am a Garmin customer since 1992, but now I am very angry with Garmin
because of this problem, I am thinking that maybe I should instead,
try sell this 276 and buy a plotter from NAVMAN or other brand: any
suggestions?

60 Days to get a software fix? That's not bad, given it's not life
threatening.

Its rigth, if you know that the problem will be fixed at all; for a
gps receiver, witch is aimed to nautical market, the most basic
function is driving an autopilot: the most inexpensive units does this
without problem.
What make me angry is that, the GpsMap276C is a very good unit,
portable, TFT displat with 256 colors, has good land features like
autorouting, and advanced marine functions like the new VHF/DSC
position report suport etc, but does not have a good NMEA "Advanced
Function" witch alow the user to select what NMEA messages he wants
the unit to send; I think that the navigator equipment (gps)should
serve the other equipments, sending what they need, not sending only
the messages someone in Garmin decides it should send.

I have a garmin 176c, And a old navico auto pilot 8000. The problem that I'm having is the garmin will
only output nema 2.0 and my auto pilot wants nema 1.5.
I tried going to advance settings and dumb down the output of the garmin, but still no go. I tried my
friends garmin 48 that unit worked ok. Still trying to solve the problem. Any help would be usefull.

Maybe you can get a NMEA multiplexer that will do the conversion for
you:

Buy an old GPS48 on Ebay. I have one in addition to my new 60CS. Well worth
the small expense, and it WAS the best around at the time. Detachable
antenna, great display, worth it's weight in gold! Cheaper than a new
autopilot!

Good solution, and you end up with a backup GPS in the bargain. The
downside is that you have to enter wayoints twice.
