RsyNav 300 GPS in GPS Repeater Mode

I have recently upgraded my navigation to use a Garmin GPS17 via a Garmin 3205 Chartplotter for my position data. I am trying to set up my old Raynav 300 as a Repeater. The GPS signal from the Garmin kit is NMEA. I have tried connecting the Garmin NMEA signal directly to the NMEA input port on the Raynav 300 but without success. Does naybody know why this should be? Also is there a way to monitor the NMEA from within the Raynav 300?

I have checked all my connections. The Garmin signal is OK when leaving the Garmin. I have also used the Raynav 300 NMEA port to upload waypoints. My assumption is that the problem is software/firmware.

P.S I gave also tried to feed the GArmin NMEA signalt onto Seatalk via a Raymarine NMEA Seatalk Interface but this also fails.

SOURCE: I bought a C80 Raymarine

I would send your seatalk (Yellow and black) from your c80 to a junction box, send your rs125 to the junction box and another pig tail seatalk lead to the J-box coming from the autopilot. Now...on the raystar 125 connect the green wire to red, and the brown to black. Now connect the reds together, the shields and blacks together and finally the yellow's. The autohelm should power up the seatalk bus enough for your gps to work. the c80 offers power from seatlk but don't connect it's red wire.



Autohelm ---------------[ ]----------------GPS

C80---------------------------

Many times the shield is the silver wire we call it that since it has no other coating except its occasionally heat shrinked on the end.

RS125 -------Green------------------------0-------------RED------------ + power
--------RED------/

--------Yellow-----------------------0-------------Yellow---------- Data
--------Black------------------------0-------------Shield----------- -Power

you will need to hook up direct. Seatalk wont handle a waypoint download, but the chartplotter will accept the data directly into the NMEA in port. All other data, like wind depth and latlon are handled by seatalk

I cannot use my garmin 300t whilst it is plugged in charging, it just shows a page with what looks like a computer tower, a cable and a satnav. i cannot navigate away from that screen

Hello,

The power cable used to charge the unit is putting it into mass storage mode. This mode is used to upload and download map data and updates to and from the computer to the unit. If this is happening when it is just connected to a power source and not the computer, it would mean that the power cable being used is not the correct one.

The recommended vehicle power cable for the Oregon or Colorado 300t will need the Garmin part number 010-10851-11 .

Says cannot unlock maps what do i do

If you recently just upgraded your maps you should have received a registration number from garmin. If the registration code does not work contact garmin at www.garmin.com. Go to the top right hand corner of that page where it says My garmin click on that and either setup an account or put in your user name and password. From there you can contact Technical support via email or by phone. They will correct your problem with registering your map software.

I hope this helps you out and if it does any positive feed back will be greatly appreciated. Thank you

I was charging my garmin 255w with usb cable into my desktop computer. I was (still am ) having problem with the dvd -cd hardware . I decided to download new software from HP to restore my drivers to the...

Hello,

Please make a resetting process to solve the problem.

Garmin is the leading GPS navigation, communication and solar devices developer in the world. Among its popular products are Garmin N?vi, Garmin StreetPilot and Garmin Zumo (for motorcyle) series of automobile in-vehicle GPS receiver and navigation unit. Garmin GPS unit allows user to update its firmware, add custom POIs (Point of Interests), Waypoints, Favorites and customize other user settings.

Most GPS navigation devices from Garmin has a reset function which allows user to access a Maintenance Mode screen with system information, diagnostic details or perform the reset function to restore Garmin Nuvi or other series unit to its original default factory settings.
Depending on which model of Garmin GPS unit you're using, the following routine can reset the Garmin device to original factory loaded settings, or bring up the Maintenance Mode with access to System Information and View Diagnostics screen, where users can see various logs, and of course, clear all user data (reset to factory defaults) or clear Waypoints.
In order to reset Garmin device or enter into maintenance mode, perform one of the following procedures:
Power off Garmin unit. Press on continuously the upper top left corner of screen and then power on the unit by pressing once on the Power button. You should be prompted to clear all user data, or asked if do you really want to start up in maintenance mode. Press "Yes" to reset (warning: all data will be erased and lost, so backup before proceeding) or enter maintenance mode.
Hack above works on Garmin Nuvi 660, 680 series.
Turn off Garmin device. Press down on bottom right corner of the touchscreen, and then power on the GPS unit. You should be prompted whether do you really want to erase all user data, or asked if do you really want to start up in maintenance mode. Press "Yes" to reset (warning: all data will be erased and lost, so backup before proceeding) or enter maintenance mode.

Note: If entering maintenance mode, it's also possible to perform master reset by selecting clear user data option.
Once the device has been hard reset, user have to perform the set up procedure again upon start up. Note that erase user data command only delete data in the Garmin unit's memory that isn't accessible to the user when the unit is connected to computer. The command does not erase .gpi or .gpx files loaded (if your .gpx files contain any waypoints then they will automatically be imported into Favorites), nor will delete any MP3 music, JPG photos or any other files that have been stored on the GPS memory card.
Once the Garmin GPS unit is reseted, remember to place the device outside where there is a clear unobstructed view of the sky for 15 - 30 minutes in order for it to requires fix to GPS satellites.
Unfortunately, even if you perform master reset on Garmin GPS unit, it does not reset Garmin Lock security feature, which password-protect most Garmin electronic devices to deter theft. If you forget the PIN or password unlock code to unlock the Garmin unit, the best solution is to bring it to Garmin to get unlocked. "Secure Location" does not unlock a locked Garmin unit either as it's only a temporary fix as when it's turn on outside the security location, the device is locked again.
Good luck.

Hello,

the problem is actually a software issue and since resetting does not solve the problem,I think updating the deice should solve the problem. Update is just like reinstall the system software of the unit and it might get things fixed.

To perform update, follow the below procedures;

1. Plug one end of the USB cable into your GPS and the other end into your desktop or laptop computer. The GPS device will load the appropriate driver automatically, and a message on your GPS tells you that it is connected to your computer via USB.

2. Open your Internet browser of choice and type in the following web address: http://www8.garmin.com/support/collection.jsp?product=999-99999-27

3. Download the appropriate version of the software for your computer (Windows or Apple) and Install the WebUpdater by following the wizard (accept defaults).

4. Click "Start," "Programs," "Garmin" and " WebUpdater" to update your firmware and your maps. Periodically check and make sure your software is current.

If the computer does not recognize the Gps, you can try the below procedure;

With the unit OFF, hold your right thumb on the Upper, Left part of the screen and plug the USB plug from your computer into the back of your GPS. The unit should boot up and stop at the screen where it shows a little computer, wire, and little GPS. Your computer should now show the GPS as connected. Only now you can pull your thumb from the screen.

Then use Webupdater to upload 4.40 to your GPS.

Hopefully, the above should be helpful

Good luck.

Street Map Program for Garmin GPSMAP 295

Detailed road map data, with addresses, hotels, gas stations, etc. can be loaded into a data-card/cartridge/memory-card using Garmin's Mapsource software such as Metroguide or City Navigator. This can be changed as needed via a PC.
The 295 does not have driving routing/guidance through the streets as most of today's GPSs have, but it will show you exactly where you are on the street (but it should be switched to Road mode).
Driving routing is possible on the PC using Mapsource, but ithe route doesn't transfer well to the 295 because of the limits on waypoints.
