Where in the world are we?
With a GPS receiver in
your car, you can finally
lay that tattered road map
to rest
By Douglas Hunter
APPROACHING Ottawa from Montréal
as twilight and rush hour set in, I surrender
to a firm yet maternal voice not unlike
that of Mary Poppins. “In 500 metres, turn
right.” The plummy, disembodied words
emanate from a magical box the size of a
wallet that is suction-cupped to the windshield,
below the rear-view mirror. On its
touch screen, a 3-D view of my progress
along Highway 417 scrolls by, the location
of my car marked by a small blue icon. I
have to reach a hotel on Slater Street, and
while I have been there before, I am no
expert on Ottawa’s thoroughfares and oneway
streets. So I am entrusting my safe
and timely arrival to the little box.
It gets me there flawlessly by painting
the ideal route in pink on the display, with
turns marked by arrows and onscreen driving
instructions backed up by Poppins,
who tells me where to turn (in how many
kilometres or hundreds of metres) and
when to keep left or right as I negotiate
off-ramps. If the unit directs me into the
Rideau Canal, I will obey without question,
since by this time, it has successfully delivered
me from my home near Midland,
Ont., on southeastern Georgian Bay,
through Kingston and on to Montréal,
where I made a similar twilight rush-hour
arrival at a downtown hotel in slanting rain.
The wise little device is a Garmin nüvi
250, a GPS navigation unit I purchased on
the eve of this extended road trip. I had
other choices — almost too many — but the
Garmin model fit my criteria of being basic,
inexpensive and made by a company whose
products I already knew from marine GPS
navigation. And, thanks to fierce competition
and a white-hot loonie, retail prices
were in free fall. The nüvi 250 has a suggested
retail price of $321.41 (U.S.), but I
had just paid $269 for it at a big-box electronics
retailer, and its competitors were
undergoing similar price cuts.
This type of device is ideal for guiding
you in stressful conditions: an unfamiliar
city, heavy traffic, darkness or inclement
weather. It comes preloaded with map software
and databases of “points of interest,”
such as hotels, restaurants and gas stations,
as well as street addresses. Simply
search the database with a touch-screen
keyboard, and the nüvi 250 quickly locates
where you want to go. The routing function
then tells you how to get there. By tracking
changes in position over time, the GPS
unit calculates your vehicle’s speed and, by using its built-in intelligence on speed
limits, provides you with reasonably accurate
destination arrival times. (Some units
even warn you if you’re speeding.) It can
also help you stickhandle your way through
a maze of secondary roads on a cross-country
expedition. Many times during a lengthy
jaunt, I have found myself suddenly wondering
whether I’ve reached a crucial turn
or shot past it. My normal recourse has
been to consult a paper road map after
pulling over somewhere or, in more reckless
moments, while driving.
The Garmin has cured me of this dangerous
habit, but there are still some safety
issues to consider. You can choose to suction
mount the device to the windshield
or fix it in some way to the dashboard. I
decided to go with the windshield mount,
just off to the right but within arm’s reach,
which I consider the safer option, with the
map in my field of vision as I drive. But concerns
about windshield mounting of any
electronic devices have caused the practice
to be outlawed in Minnesota and California.
Pre-installed in-dash systems, available
on high-end vehicles, have larger screens,
lack the clutter of wiring (which plugs into
the lighter) and are usually integrated with
the car’s audio system. Some even have
DVD-playback capability and presumably
are meant to be watched by back-seat passengers
or by the driver when the car is
parked. An advantage of a portable unit is
precisely that: it’s portable. You can also use
it while travelling on foot, running it on
battery power. And this way, you don’t have
to buy an entire luxury car to get highquality
GPS navigation.
