I just hooked up my JRC Nav 500 GPS to my Standard Horizon VHF. I pushed
the Nav button on the VHF and there was my position, speed, bearing and
date/time. Shouldn't need any sort of initialization and I would not think
the Garmin and Icom would be incompatible.
I find the designations used by the various manufacturers for NMEA data in /
data out to be confusing. You never know if two different manufacturers are
describing things the same way. Its possible you just have the wires hooked
up wrong.
On my setup the GPS had DataOut + and DataIn +. These were the only two
wires I hooked up to the NMEA In / NMEA Out wires on the VHF.

The only other thing I can think of is matching the NMEA output speed from
the Garmin to whatever is spec'd for the VHF.

As for checking for a NMEA data stream, you can do this using a laptop
computer by using Terminal mode. Once again you will be faced with
connecting the correct GPS wires to the correct wires on a serial plug that
goes to the laptop. The manual for your Garmin should tell you which NMEA
strings it outputs. If the GPS is working its likely the NMEA output is
working so I'd concentrate on the connections to the radio.
Good luck.

Amen.
I have two Garmin's, two VHF radios and a radar. I had to email Garmin for
assistance in wiring for each of them. The good news is that Garmin is quick
to answer email.
I not only told them what equipment I was connecting, but quoted the
manufacturer's instructions, because they don't all use the same
terminology.
Remember to set the Garmin for NMEA/NMEA, and maybe not the fastest speed.
I found that my radar doesn't seem to detect the information at the fastest
speed, but is OK at slower BAUD speeds.
If it's a new Garmin, you may have to manually initialize it. When I travel,
my Garmin sometimes takes a long time to figure out where it is, so I
manually initialize it for the new location.

Have you set the garmin to NMEA? Factory default is probably Garmin
protocol. Set it to NMEA and, if possible, select 4800 baud.

Under main set-up there is an option to change the interface set-up.
Change it to NMEA out.. don't think there is an option for baud rate.
This will get it going no problems.

I have the config set the way the Garmin tech. told me on COMM2 .The
baude rate is not an option to change. The wiring config. should be ok
because both the Garmin and Icom techs e-mailed me the wiring diag. and
I feel comfortable that the wiring is ok. The connections should also be
ok because I cut and spliced them about 5 times and still could not get
anything.
I ck to see if the the gps is communicating with the vhf by pushing the
"POS/DSC" button for a few seconds and it should show my position on the
vhf screen but it shows "NO POS" whitch according to the Icom tech means
the gps is not communicating with the vhf. I don't if the gps is
receiving from the vhf to plot someone elses position on the vhf
screen. I don't know anyone in the area to ck it with

I have the exact same problem and have found no solution.

Check in the VHF manual (or ask support) which NMEA sentence is expected by
the VHF. Check if the GPS is configured properly (baud rate 4800, NMEA Out)
and make sure the version of NMEA that you have selected includes the
sentence that the VHF requires.

getting back to Speckfisher's original post, is there a way to test
NMEA out/in with a meter, or do you need a laptop/software to do so?
 >> Stay informed about: Nmea /dsc 

what is a terminal program? remember, you are dealing with someone who
knows NOTHING!

thanks for great information. Some day, I may actually get it!

You can see if an NMEA device is outputting data using a voltmeter. I
prefer an analog meter, but DVMs can also work, unless they are very
slow reading.

Set the meter to read 5 volts, and, if there is data present, you
should see it wiggling - with the voltage varying around 2 - 3 volts.
The data line will acutally switch rapidly between 0 and +5 volts, but
the meter won't be able to follow it.

What is this? Didn't know VHS had com ports?
 >> Stay informed about: Nmea /dsc 

Both the Garmin and the VHF have two ports.
The VHF has one to receive GPS info from the Garmin, which is displayed on
the VHF and transmitted with DSC, and another to send received info (from a
DSC reception) to the Garmin so that it will be displayed on the Garmin.

But in this case we're talking about COM2 on the Garmin....
