Have you checked to make sure that your serial port is enabled in your computer bios.

to check:

some computers require you to press del while booting other esc.

the message should read somthing in the line

press ???? to enter setup

go to the advanced tab

look in IO (Input/Output) devices or somthing similar.

Make sure Com1 or UART is enabled.

If the device is enabled, then check to make sure that your cable is making a connection properly.

(May require you to open up the unit) if out of warantee

To check that the cable is connected properly on the outside contact to db9 port.

Pin 1 2 5 are used on the db 9

on the inside there is a cable with 4 wires soldered to a board which links the outside to the inside.

Connect your serial cable to the GPS, using a multimeter check continuity by holding red lead on pin 1 of db9 serial port and checking each pin for continuity. only 1 should indicate continuity, continue with pin 2 and pin5 on serial port connector.

If you are sure that there is connection between cable and GPS, check the cable from the soldered points to the GPS Board. If those are ok, then you may have a problem on the board. Would then sugest you take it in for checking.

How to register my 1450lm


Hello,

Create an account on Garmin's website and register the GPS using the serial number or plugging the GPS into the computer after downloading the Garmin communicator plugin.
The Garmin communicator plugin is an application that allows the GPS to communicate with the Garmin website.

https://my.garmin.com/mygarmin/login.htm?service=https%3A%2F%2Fmy.garmin.com%2Fmygarmin%2Fcustomers%2FmyGarminHome.faces

After the GPS is registered, there will be a tab for the "Dashboard" and with the GPS connected to the computer, the dashboard will detect the serial number of the GPS and let you know if there are any software or map updates available for it.
The Garmin WebUpdater program can also be used for updating just the software (firmware) of the GPS and is a free download.

Since new computers don't have serial ports I assume this is an older computer. The older computers had usb ports that were usb 1. All devices now are usb 2.0 Could this be your issue?

What is the make and model of your computer?

How to interface a furuno 1833c navnet to a usb port and how to download waypoints to my pc.I have the older 9 pin pc cable and a usb adapter cable.Looking for usb drivers and software to make it work.


The display uses a serial interface, otherwise known as a comm port. You can get a USB to DB9 adaptor practically anywhere. Once you have a serial connection, you will need software such as MaxSea to send the waypoint with.

Connecting Garmin Foretrex to PC


Hi, I just wanted to let you know that I have been having problems downloading the wayponts but not the tracks. I use Street Atlas USA and have NO problems downloading all data with my garmin GPS12. I notified garmin about this problem. To see if your gps is recieving data try using the geocaching.com web site. Sign up [ it is free ] and click on an icon cache in yoir area, then click on send to gps. You will be prompted to download free software to use it. Once it is installed, try the above option again. You will get a menu that shows devices shown. Look for the fortrex and send it to the gps. Make sure your gps is in " GARMIN " mode for the interface. If it shows your fortrex then it is communicating with it. Download the cache to your fortrex and then look at it in the waypoint file of the gps. The web site is :http://www.geocaching.com/

Hi fire1961,

Downloading data from my FURUNO GP-30 gave me no problems. But it took me long time to figure out why I coudn't upload waypoints and routes to the GP-30 via the serial port in my ThinkPad T30.

I tried nearly everything tested the cable, tested a lot of different software and even wrote a little c-program to communicate with the serial port. I also tried a serial-to-usb converter with no results. Then I stumbled over this RS232 Tutorial. According to this - serial ports are not just serial port but can be divided into three general categories:

The types of driver ICs used in serial ports can be divided into three general categories:

* Drivers which require plus (+) and minus (-) voltage power supplies such as the 1488 series of interface integrated circuits. (Most desktop and tower PCs use this type of driver.)
* Low power drivers which require one +5 volt power supply. This type of driver has an internal charge pump for voltage conversion. (Many industrial microprocessor controls use this type of driver.)
* Low voltage (3.3 v) and low power drivers which meet the EIA-562 Standard. (Used on notebooks and laptops.)

Then I installed the waypoint upload software to my ten years old Compaq Presario and suddenly I could upload routes and waypoints but only via the on board serial port. The serial-to-usb converter didn't still work.

So if people experience no result trying to upload data to these old GP-30's from their notebooks and laptops. Then I think it could be a matter of these Low voltage ports not are able to provide the FURUNO device with enough voltage. See the above RS232 Tutorial.

Best Regards

Garmin GPS III Pilot to PC communication problem


If it were doing this just on the Vista machine I would say it was Vista related but since you are getting it from an xp machine as well the problem is either cable or the gps unit. You don;t say if this just started happening or ? If you can try out the cable on something else to make sure so you can eliminate it. About the only thing you can do is to make sure the port settings in the pilot are set correctly. Generally the slower the better if you are having communication problems as this makes the signal timing not as critical. Try 9600 baud to start. Make sure that the data bits are also set roght. This is the 8n1 or 7n1 thing you see. I can;t think of what the default is on the garmin but as long as both pc and garmin have speed, bits, parity, and stop but set the same they should talk.

Try to download from the unit as well as upload.Unfortunetly you can only change the speed and protocal or reset the unit. You won't be able to fix it if is a hardware thing. If you are using a USB to Serial adapter then I would say that is your problem or could be. Cheaper ones just don't work often on higher port speeds. You might want to try the gps on a pc with a actual serial port if you are using one. If it works then you should try a different brand of adapter or really slow down the speeds.

This won;t solve it unless you luck out but it should let you know where the problem is.

PC will not detect Legend GPS


Change the interface setting to NMEA Out and see if that helps. That is what I did on my Legend, bought in 2003. It still crashes the computer every so often, however, and I haven't figured out why.
