Customer review from the Amazon Vine™ Program ( What’s this? )
The GPS market has come a long way in the past few years. A decade ago, there were very few after-market GPS units, they were mostly expensive, and they were also mostly mediocre. The best units cost more than a thousand, and while they’d get you from here to there, didn’t feature a lot of bells and whistles. Factory installed GPS units–then limited mostly to high end cars–generally cost $2-3k.
A growing number of portable GPS units have come to market in the past 5 or so years. Over time, the hardware has improved, the software has (for the best ones) gotten pretty good, and prices have (especially in the past year or so) dropped tremendously. (That last point–the tremendous drop in price–has forced many manufacturers out of the market. At this point, it is mostly dominated by names like TomTom, Magellan, and Garmin). There is also now competition from high end smart phones, most of which have a GPS unit built in.
(Amazingly–or perhaps not–the cost of factory installed car GPS systems has stubbornly remained around $2,000!)
While there has been substantial brand attrition in the GPS market, there is no shortage of choices. That’s because each manufacturer now offers an almost ridiculous number of models, many of which are only modestly different.
GPS units can basically be differentiated as follows
1) Screen size (usually 3-5″ diagonally)
2) Ability to acquire a GPS signal
3) The GUI (graphical user interface) presented to the user
4) Quality of the maps (how often updated, what geographical regions they cover)
5) Does the unit incorporate traffic data?
6) Quality of routing (how good are the driving instructions generated)
7) Does the unit offer text to speech? (Does it tell you the names of streets, or just say “next left”?)
8) Does the unit offer voice recognition
9) Does the unit incorporate blue tooth to communicate with your phone and/or FM transmission to play over your car radio?
10) Does the unit have expandable memory; play mp3s; etc?
11) How good is the included mounting hardware?
Let’s take these features one at a time for this particular GPS, the TomTom XXL540TM
1) The screen size of this unit is 5″. This is at the high end of current offerings by the major GPS manufacturers. This doesn’t really buy you any additional “real estate”, i.e. the resolution isn’t higher than the small GPS units. It’s just a little bigger. That IS useful, to be honest, and is also helpful as it makes it easier to maneuver the touchscreen menus.
2) This unit, like all the current TomTom line, does a great job of acquiring a GPS signal. It can take far less than a minute with clear lines of sight, and my unit was even able to pull up 5 satellites inside my home with the blinds drawn. I also have GPS units from Sony and Garmin, as well as a built in unit in my car. The TomTom is better than the Sony at getting a signal, as good as the Garmin, and slower than the built in in my car (not a fair comparison, since the built in gets a much larger antenna).
3) This TomTom has a very good GUI. The touch screen is reasonably responsive and most everything appears where one would, intuitively, expect it to be. My biggest complaint is that there are a LOT of options and option screens you can drill through–way too many to deal with while driving. The upside, is there is a “simple menus” options that will present only the most significant option screens. It should be noted that some of the recent TomTom models (e.g. the 550) have eliminated a lot of the options/option screens, leaving ONLY the “simple” menus. That is a big negative, since some of these deep menus are quite useful. Bottom line: Good GUI and stick to a model like this that at least gives you the option of the deep menus.
4) The map data is good, and this particular GPS comes with lifetime map updates. TomTom also has a “map share” facility, which allows users to upload/download map changes. That means if a bunch of users discovery that a street is closed, they can note this information on their GPS and that info will get transmitted back to TomTom, who then shares it with everyone else. In this way, maps get corrected very quickly. This unit includes maps for both North America (US/Mexico/Canada) and much of Europe. The inclusion of European maps will be considered a major bonus for some, and irrelevant for those who don’t plan to take this outside this continent.
5) This unit includes lifetime traffic data. The value of this data will depend on where you live. Major cities have great coverage. Smaller cities frequently get poorer coverage. The traffic data is also sometimes incorrect. But on the whole, the traffic data is good, and reasonably reliable (where you can get it). It is transmitted over the FM frequency, and an antenna is built into the auto…
