Is your unit performing at its best?

Did you know that there may be a free upgrade to your present GPS receiver? No you don’t have to return the unit to the manufacturer for upgrading. If your GPS receiver has a capability to attach a PC interface cable to a computer, you or anyone who is computer literate may install the upgrade. These upgrades to the operating systems provide a variety of improvements for the unit and/or correct some shortcomings in design or software. As an example, some of the upgrades provide a doubling of the amount of waypoints, routes and track back features, and include different viewing screens and operating speeds. Some of the upgrades even provide a change in the satellite reception of a non-WAAS receiver to include the new WAAS satellites, thereby making the unit much more accurate.

However, and you know there is always a catch, you should note the cautions when considering whether to install this revised software in your GPS unit.

The download offers free firmware upgrades for select units. Not all models have an available upgrade. These upgrades are specific to the model GPS units and software versions listed. This software should only be uploaded to the unit for which it is intended. If this software is uploaded to a GPS unit other than the product it is designed for, it will render the unit inoperative. The GPS unit then will have to be sent back to the factory for repairs.

Another consideration with using these downloads is that the new software may overwrite or delete all waypoints, points of interests, routes and track back data saved in the unit. This means that you should back up all of your waypoints and routes by saving them to a file on your computer or by making a hard copy printout prior to attempting the upgrade.

Be sure to read all of the information about the software, how it affects your receiver and the risks involved.

If the software upload fails, and subsequent upload attempts prove unsuccessful, the unit may need to be returned to the manufacturer for service.

I have included Magellan, Garmin, Brunton and Lowrance as several of the manufacturers of GPS units that offer free downloads for their consumer equipment. The GPS model with the latest version of available downloads is listed as of the date of this column. More downloads are continually being added. While researching the topic, I discovered that four additional models were added to the listing. I suggest that you visit your manufacturer’s web site regularly and ascertain if they provide a more current software download. As I said, if your unit is not listed, check the manufacturer’s web site for additional information.

You can check the version of your software by observing the screens when you first turn the unit on or by going to the “System Info” button or screen.

Brunton can be reached at

Their Multi Navigator System has a software upgrade that can be accessed on their support page. You can download Multi Navigator System v 2.15.

It is very refreshing to see these companies offer the support that they do. It is very comforting to know that they are available to assist the consumer in getting the most out of this high-tech equipment.

Again, I must emphasize caution when opting to download and install the new upgrades. Be sure that you completely follow all of the instructions.
