Article - How to choose a GPS

Which Manufacturer?
Chances are, you have already heard the name ‘Garmin’ when talking about GPS anywhere in South Africa. This is due to the fact that Garmin have by far the largest chunk of the GPS market share in this country. When we started this business in 1999, we did extensive research into the recreational GPS market from a GPS dealer’s point of view. We weighed up factors such as the backup and support from the distributors, the quality of the GPS systems themselves and the availability of map software.
Garmin have always had a rock-solid reputation for the quality of their customer service and support, as well as being light years ahead of the competition with regards to the map software technology and even with the GPS systems themselves.
A bit of research into the ‘Civilized’ world however (Europe or the USA) , would really blow your mind. The choices available to our overseas brethren are astounding. Understandably, with so much competition over there, Garmin have a much smaller market share and manufacturers like TomTom, Navman, Magellan and DeLorme are well represented.
It is important to remember that while it is relatively easy to buy and import one of these ‘other’ GPS units from elsewhere in the world, very few of them produce maps of South Africa for their systems (and those that do have SA maps are so far behind Garmin/Garmap with their area coverage, level of detail and accuracy it’s really not funny). Also remember that since most GPS systems utilize proprietary data formats, no other map products will work on these units. Just to be clear here - THERE ARE NO SOUTH AFRICAN MAPS AVAILABLE FOR ALPINE, NAVMAN OR DELORME GPS SYSTEMS!!!
What are my requirements?
We would suggest sitting down and going over the list of questions below, then taking a look at the Comparison Charts on our website before making a decision.
- First look at where you will use the GPS - Will it be mainly road navigation or in a City, or do you plan on using it handheld and outdoors?
- Will it only be used locally or also overseas?
- How will you use it - Will it be mainly vehicle based or will it be handheld?
- Do you have specific needs - Area calculations, electronic compass, accurate altitude readings (relative), lookup addresses of clients or even obtain accurate speed-readings?
- Are you looking for a specific functionality like a training manager for athletes, marathon runners, cyclists or canoeists?
- Will you need to use it in an environment where you will need an external antenna?
- Do you need to connect the GPS to a PC, Notebook or Laptop to upload and download waypoints, tracks or routes?
- Would you prefer a colour screen that is easier to see in direct sunlight or will a grayscale screen be sufficient?
- Do you need specific mounts or other accessories (bicycle mounts, marine mounts, cigarette lighter adapters etc)?
- Do you require additional map software (East Africa maps, SA Topographic & Recreation maps etc)?
- What sort of memory would you require for all the maps you would intend using?
- What is your budget (including accessories and additional map software)?
Comparing the different GPS models:
Since most Garmin GPS units were designed with a fairly specific purpose in mind it should be easy to compare ‘like with like’ for those particular applications. For instance when looking for a handheld GPS for hiking, one would only need to compare those units that are small, rugged units with basic functions, a good battery life and enough memory capacity for a small number of local maps. This narrows down the number to choose from rather nicely.
It is only when you start comparing units for use over a number of very different applications that it all starts looking rather complicated…
“I want a small waterproof handheld GPS with a reasonable sized colour screen, excellent battery life, with a huge memory capacity for loading multiple large maps to be used for hiking, biking, boating (it must float), fishing and micro-lighting over weekends. It must also have search & lookup features, autorouting features with voice prompts for finding addresses and routing me to my meetings during the week. I want to load marine charts, detailed streetmaps and Topo maps for hiking and I want the whole bundle for under R3,000″
Ummmm, yes, well… and I would like Telkom to give free (uncapped) ADSL to everyone in South Africa!!! Sorry folks… it’s just not going to happen.
Choosing a GPS is always going to be a compromise between competing objectives. Whether you want a GPS for offroad 4×4 and city use, marine and handheld outdoor use, offroad 4×4 and International travel or any other multiple combined applications, it is always going to be difficult to select the right one. We would suggest trying to figure out the percentages of each application that the unit will be used for (i.e. 80% city and 20% outdoor - this makes it a bit easier to possibly sacrifice some of the portability or “ruggedness” if you are going to use it outdoors only for limited periods of time or maybe for “offroad/outdoors” use but in still safe inside a vehicle and away from the elements).
Price vs. Functionality:
As with all technology, the more bells and whistles the GPS unit has, the higher the price is going to be. First look at the basic functionalities needed and make a choice. If your choice is still nicely within your budget, then only start looking at the ‘nice-to-have’ features. For those of you just trying to stay ahead of the pack with the latest and greatest gadget on earth - be prepared to upgrade at least twice per year. More bells and whistles are added every year and although most of these new features are not necessities (the necessities were sufficiently covered a couple of years ago), they are still VERY useful and ‘nice-to-have’.
Hope this helps a bit…

Good morning.
I recently asked a surveyor from quotation to map a 13.8 hectare property, including the position of large trees, borehole, cables, roads etc, and it dawned on me, after receiving the quote that I could probably buy a GPS unit and mapping software for less than the quote. I fully understand that, going that route would not give me the same degree of accuracy, I still figured it would be sufficient for my purposes.
My question to you becomes: what should I buy?
Further to the above requirements, I would very much like to be able to use the unit off-road, in particular, on my adventure bike. I will probably also have very little need for streetmaps, though I suppose it could become handy at times.
Thank you. Martin
Hi Martin
Yes, your accuracies would be nowhere near a surveyor quality DGPS (Differential GPS) system. Please read our post on Navigation vs Mapping. For those planning to use their GPS for ‘critical’ accurate measurements (e.g. Farmers needing to measure fields to calculate crop yields, requiring accurate heights for pipeline and irrigation purposes and also for collection of any positional information that will be entered into any GIS database, used by utilities services companies etc) then the accuracy of these handheld “recreational/navigation” GPS units are of real concern. Such requirements are best met by using DGPS.
That being said, I would recommend either the Garmin GPSMAP 60Cx or the GPSMAP 60CSx. Ideal for outdoor or offroad activities and with autorouting (but no voice prompts) for city use - you can’t go wrong with one of these babies
Good day;
I am interested in buying a GPS but with all the different manufacturers and models out there I’m lost.
I need a GPS that can help me navigate in town (60%) from customer to customer but also exploring Southern Africa (40%) (Namibia, Botswana, Zimbabwe, Mozambique, Swaziland, Lesotho and of coarse South Africa) travelling off the beaten track and some times making my own road. Although it would be used for off road purposes it would mainly be secured in the vehicle. The ability to mark way point and go back to them later would be nice.
Is there any entry level unit that would satisfy these needs or must I go for something higher up the range.
Thank you.

Hi Christiaan
Unfortunately, the “Autorouting” feature (the ability to search for addresses and have the unit select the roads for you to travel) is not available in the Basic units - this is more of a “Street Navigator” function. There are a couple of cost effective entry level Street Navigator units available, however they are not really designed for off-road/outdoor use (not as robust or waterproof as the outdoor units) and whilst they could theoretically be used anywhere, they do not have the additional features that are usually regarded as important in an outdoor unit (eg. tracklog functionality).
I would suggest looking at one of the dual purpose units like the older Garmin Quest or even the new Nuvi 710 (personally, I would recommend the Nuvi 710 unless you are going to be doing any hiking or other strenuous outdoor activity with it).
Oh yes, and please sign up for our free email course “What you should know before you buy a GPS”
Hi
I am sick and tired of getting lost from A to B. I therefore decided to look at a navigation system. I mostly travel to different customers, mostly Pretoria and Johannesburg, but sometimes need to see people on farms in the Brits & Rustenburg areas.
I can afford +/- R2500.00 at this stage.
A friend of a friend offer me an audio box for R2200.00. Would that be sufficient?
Can you please help me with a suggestion.
Hi Mariaan
Merry Christmas
I recommend that you take a look at the Garmin Nuvi 200 or Nuvi 200W.
I am hiking across Iceland in August and we need a GPS. What would you recommend as a lightweight model, and where can you get the software for Iceland maps? Or do you even need Iceland specific maps if you have the co-ordinates and way points? What would be the best and safest way to go?
Regards
Jason Suter
Hi Jason
If you are just looking for a unit for a “once off” use, then you could go with the cheapest “Basic” (non map-enabled) outdoor model in the Garmin range, the Garmin eTrex H. Cheap, lightweight, good battery life, basic, rugged and easy to use. There are no detailed GPS maps available of Iceland at this time so a map enabled unit for this adventure would be overkill.
If however, you would be using the unit for other purposes after your Iceland expedition, then I would strongly suggest thinking about any other features that you would need in the future and where you would be using the unit. Detailed maps, where available, take up memory space so (preferably) expandable memory capabilities would be needed etc.
Hi
I want to get a GPS for motor use, mostly in the city.
The thing that puts me off the most is having the car charger wire hanging from the unit to the cigarette lighter and generally getting in the way of the gear lever.
I understand that the best place for the unit is probably the windscreen or the dashboard, but is there a way that the unit can be wired in so to say, without coughing up R12K to BMW??
Thank you
Gordon
Most people who want the GPS to be “hardwired” into their vehicle simply pop out to their nearest auto electrician and have the job done for a few hundred Rand. Not sure what BMW’s warranty policy is but it’s generally not a major job to run the cable behind the dashboard and connect it to the back of the cigarette lighter socket.
Makro has the garmin 610 on special this is a discontinued unit but has many features for a good price would you recomend that i buy
My daughter is going to Ghana (from USA) and I was looking at getting her a GPS unit strictly for emergency use. I want her to be able to call the embassy and tell them exactly where she is if she is in trouble, using Lat and Long coordinates. The retail salesman here in Texas said the Garmin eTrexH that is sold here would not work in Africa due to software constraints. He says the software is optimized for use in the US and wouldn’t interpret the signals from the satellites over Africa correctly. Is that true? I couldn’t find anything on Garmin’s website about that.
Thanks for your help.
Hi Mark
This must be the funniest thing I’ve heard all week
A GPS receiver will receive satellite signal, and be able to give you your co-ordinate position, in any country in the world. It is only the detailed map software that is loaded onto the “map-enabled” category of receivers that would be country (or in some cases continent) specific.
Since the Garmin eTrex H is a non map-enabled unit, there would be no problems using it anywhere.
Thank you very much.
I read that TomTom has Zulu,Sotho,Fanagalo,Afrikaans, etc. voice. Basically i just want to be able to go from A to B in Gauteng with ease. So, which TomTom or Garmin product should i compare?
(I want to look at the two and say “this one does the same as the other but for a better price”)
