GPS Cable FAQs and Software Links.
There is lots of excellent information, software and FAQs for Satellite
navigation receivers (and quite a bit of Garmin specific information) held on
Peter Bennett's Web site.
One of the biggest GPS information sites is
Joe Mehaffey and Jack Yeazels's
, and in Germany Thomas Born has a
Garmin specific site
with lots of information. For Psion 3 users
here is a site
with software and connection information.
WHERE CAN I GET THE SOFTWARE I NEED TO COMMUNICATE WITH MY GARMIN?
There is quite a lot of PC software available, check the above Web sites, or
try a Google search, but we have successfully used (or tried) the following
software programs to manage the information on our GPSes:-
Gardown is a tiny DOS program to up and download information to the GPS, and is very quick and
convenient for backing up data. This site has a copy of the last version we know of.
a free Windows application that can transfer Waypoints, Routes and Tracks between
your GPS and your PC (and vice versa)
is a fast, free, and easy way to create, edit, and transfer waypoints and routes between
your computer and your Garmin (or Magellan, or Lowrance) GPS. (EasyGPS is part
of the TopoGrafix family of outdoor products).
a free Windows application which can also display tracks and routes on screen.
a shareware Windows application that can also superimpose tracks and Waypoints
on scanned map images.
another Shareware Windows program with similar capabilities to GPS Utility.
As we mentioned, there is other software that you can find using
including applications for Palm, Psion, Windows CE and Pocket PC. For Windows
PCs, GPSS and OziExplorer are worth looking at for very feature rich (but not free) software.
We are happy to receive cheques in Euros or Sterling from you when you have
received your cable. A self-addressed envelope is enclosed with the cable to
make this even easier.
Older Garmin GPSes cannot 'talk' to a USB port directly (you would need one of our
USB to Serial converters to enable this) so a nine-pin serial port is best. Newer ones have
USB connectors, but only Garmin's own software seems to be able to use this.
IS IT BETTER TO USE A SERIAL OR USB PORT?
There are lots of possible reasons for this, but one of the most common is that
another program is already using the serial port (for example a Palm or Psion
or Handheld PC). The syncronisation software for these devices often grabs the
serial port when the PC starts up, and doesn't let it go again. Try stopping
the software (or even uninstalling it to test).
WHY DOESN'T MY DATA CABLE WORK?
To check if it is a problem with the connection (rather than your GPS
communicating software) you can use a terminal emulation program (such as
HyperTerminal included in Windows). Set your GPS to produce NMEA output (check
your user manual) as this produces continuous text output. Open the terminal
emulator application and connect it to "direct to COM" for the COM port you
have plugged the GPS into (this is usually COM1 or COM2). You should then see
a stream of characters with lots of lines starting $GP If the text instead
looks like a lot of strange hieroglyphic characters, the connecting Baud rate
is probably wrong (it needs to be 4800 Baud for NMEA).
If this basic test works, then the problem probably lies with the software you
are using, if it doesn't work then you may have some conflicting communications
software, not have configured HyperTerminal quite right, or you might have a
faulty cable. Let us know what you have tried and we'll be happy to try and
No, unfortunately it doesn't, but later versions of these Microsoft's programs
DOES YOUR USB RS232 CABLE WORK WITH AUTOROUTE 2001 (AKA STREETS AND TRIPS 2001)?
YES! We have (signed) XP drivers on CD-ROM that comes with all of our USB
DO YOU HAVE XP DRIVERS FOR THE USB CABLES?
If you have a GPS that uses 12V or more, we can supply a power cable that has
bare wires, with no connector. This will be suitable for you to adapt as you
I AM A BIKER. DO YOU HAVE A CABLE THAT I CAN WIRE STRAIGHT INTO THE 12V BATTERY
ON MY BIKE?
If you have a Garmin that uses less than 12V (3v-5V) you should then use the
voltage reducer from our eP3 Cigarette to GPs power cable. you can dissassemble
the power reducer on the end to either make a plug to plug into your bike, or
to wire the cable straight into the battery on your bike.
No, you won't lose the USB port if you install drivers and yes, you can change
I WAS INTERESTED IN YOUR USB RS232 CONVERTER AS A BACKUP TO GIVE A SECOND
SERIAL PORT ON A NEW LAPTOP. IF I HAVE TO INSTALL DRIVERS DO I LOSE THE USB
PORT OR CAN I CHOP AND CHANGE BETWEEN USB AND SERIAL?
We can supply 1.8 m long 9-pin female to 9-pin female null-modem gender changing cables. They cost £6.00 including p&p (£5.00 if ordered with another cable).
WHERE CAN I GET A NULL MODEM GENDER CHANGER?
The standard eTrex cannot display maps: so no you cannot download them.
Collections of Waypoints have been published on the Internet. Just use the
Google search engine to look for them. Examples can be found at
. You will need software to run on the PC and this is available for downloading
as well (see the first question above).
CAN I DOWNLOAD ANY SHAREWARE MAPS TO THE eTrex WITH YOUR ED1 CABLE?
