I've got the Ventura in the shop having some glass work done. In 2003 during one of the hurricanes a rather large gum tree landed on the roof of our house, the Ventura, and our VW. Had it repaired but some rather deep spider cracks that have reared their heads. So I'm getting those taken care of.

So with some down time, I decided to remove the electronics housed inside the the console just in front of the helm. I'm removing a 6 year old Garmin 2206 (still running strong) and a ICOM 504 (already sold). I'm adding a new Garmin 740 (without SONAR) and a Standard Horizon GX2100AIS VHF Marine radio and AIS receiver.

Before I took the Ventura to the shop I removed the existing pieces so when I get her back I can just install the new backboard with the new stuff ready to go. I installed the two new items on the new backboard tonight and ran some table top checks to make sure everything worked as advertised. Here are some pictures of the project.

The old setup

The new setup--however, not on the boat yet.

The Garmin 740 is a breeze to flush mount as you can see. The biggest item is cutting the hole for unit to fit in. Four bolts with hat nuts later your finished. I pre cut a thin rubber gasket and placed between the unit and the wood backboard. Makes for a more vibration resistant install.

The blue area is where I plan to place the NMEA 0183 buss connector strip so I can connect the Garmin to the SH. Garmin%20740%20and%20SH%20GX2100%20Install/8-1.jpg?t=1274330270

I fired everything up to ensure it all worked as advertised and to make the latest software updates to the Garmin. The new GPS receiver embedded in the 740 is extremely sensitive. It was able to lock onto seven birds from my kitchen table. I have alot of tall pine trees around my house so I thought this was noteworthy. You should not have any issues flush mounting this unit inside an electronics box.

I'm fortunate in as much as I can install all the equipment off the boat and then take it to it when I'm finished. I connected everything up today including the GXM 51 smart antenna to test it out. While I had it on I called XM and cancelled my subscription for my GXM 31 connected to my Garmin 545 and added the GXM 51. The whole process including the call to XM and getting weather data on my 740 took 30 minutes start to finish. Got to love those folks.

Here's a couple of pictures of the NMEA 2000 backbone and NMEA 0183 connection.

I'll post some more as I move to the boat.

Tom congrats on your new toys :) My only gripe was the extra $18-USD for the flush mount brakets for the GX2100

Did you get the PA horn to match ?

I thought it was good of Standard-Horizon to put the interface wiring diagrames for different GPS and plotters on their site.

Thanks Steve--got the flush mount kit for $9. I asked the question of a couple of the vhf manufacturers why the additional cost for flush mount kits. The response: over 75 percent of new users bail-mount their VHF radios, so that's why they make the flush mount kits optional.

Outstanding presentation. The look of your work is perfect even for an OCD guy like me. As you may know I'm about to install an almost identical set up on my 190 Montauk. The differences are that my Garmin is a 740S and the SH VHF is a GX1500S. My plan is to mount them side by side as you have done. I'm amazed that you are getting a 10' estimated position error inside your home using only the internal GPS receiver.

I have a couple of questions if you don't mind.

Is the 0183 connection strip simply standard electronic stuff or is there some special feature about it?

Does the 740 come with a cable for the 0183 connection for DSC?

I'm highly nervous about cutting two large holes in the front of my console. The Garmin template shows what size drill to use to achieve the correct radius in the corners but the SH template does not. What size drill bit did you use for the VHF cutout corners? I've never cut into a console before except with a hole saw for the huge first generation Lowrance cable connectors. I have heard a lot about how to approach the job but I need to bolster my confidence with some more reading.

I'd use the same drill size as recommended by Garmin. When I cut into console faces I do it a little different than most. I offset the drill holes a little from the corners and use them as a starting points. I use a higher end Bosch hand jigsaw to cut the template hole. I cut the straight lines spec'd to the cutout template and in the corners I cut a little inside the lines and use a Dremel rotary tool to fine tune them. Before I do any fine tuning I check to see where I stand with the current cut by placing the item on top of th hole and looking underneath.

The 740 power cord comes with the NMEA 0183 contections. There are NMEA 0183 ports on the 740. The white connection bar you see im my pictures comes from Radio Shack. They're about four inches long and be cut to the size you need. I've used this item to make NMEA 0183 connectionsgoing on six years and havce never had any connectivty or failure issues.

If your going to connect the power leads to a fuse block Garmin recommends cutting the inline 3 amp fuse out and replacing it with a 3 amp blade fuse at the fuse block.

Here's a picture of the 740 power cord leads. Garmin%20740%20and%20SH%20GX2100%20Install/GArim740PowerCord. jpg?t=1274451934

In regards to the internal GPS antenna .... it is super sensitive to say the least.

Bluewater: Your console looks like the dash board of the space shuttle. How can you pay attention and drive the boat with all of that stuff?...Take care

Pretty easy for me ... this is what I did in the navy for 31 years. It's in my blood. Garmin%20740%20and%20SH%20GX2100%20Install/CDC1.jpg?t=1274455840 Garmin%20740%20and%20SH%20GX2100%20Install/cdc2.jpg?t=1274455966

Spent many and hour in CDC/CIC sitting infront of all those display and manipulting data. When I sat Tactical Action Officer watches would spend 12 - 14 hours straight watch 14 large screen displays. You get used to sorting thru a bunch of visual data. The advent of color helped out big time.

Here's a 11 plus minute video of the 740 displays and functions. Will post some later.

Nice unit!

The Garmin 700 series has the ability to screen capture. It is selectable either ON/OFF default is OFF.

You turn it on from the Home Display by selecting

Configure>System>Beeper/Display>Screenshot Capture ON/OFF.

To capture a screen first insert an SD memory card in the units SD card slot, next select the display for capture, next press and hold the Home Key/Menu for six seconds. When the unit is finished capturing you will see a screen prompt Capture Complete press OK to return to Main Menu.

Here are some actual screen captures. These are to scale in relation to the 700 series display screen.

I finished the wiring between my 740/GS2100 now all I have to is install the backboard when I get my boat back. As you'll see I used just about every inch of space on the backboard.

My objective was to make this a one stop install so as to keep everything on the backboard that way it's all infront of me & easy to add to in the futire.

Fired it up tonight and everything worked. XM Weather, two way DSC comms, AIS data making to the 740 with all the bells and whistles .... I'm one happy camper for sure!

Here's some pictures. Garmin%20740%20and%20SH%20GX2100%20Install/3-1.jpg?t=1274667462 Garmin%20740%20and%20SH%20GX2100%20Install/4-1.jpg?t=1274667500 Garmin%20740%20and%20SH%20GX2100%20Install/5-1.jpg?t=1274667550 Garmin%20740%20and%20SH%20GX2100%20Install/IMG_5180.jpg?t=1274666322

There you go.

Tom--I would very much like to see a screen capture of the GARMIN display when showing AIS target information received from the Standard-Horizon radio. I know you are still shore-based with this new rig, but as soon as you get in range of some AIS-equipped vessels, please show us a screen shot. Thanks!

Tom--I really appreciate your excellent photographs and particularly the use of callouts to identify components in the photographs. Thanks for these. They are all very interesting.
