Accord GPS "time to destination" error
A good friend has a new Accord with the GPS navigation system. For
whatever reason, while it perfectly pinpoints his location, the estimated
time to destination is off a good 30%. It's as if the system is reading
the car's MPH with a 30% error on the slow side. However, the car's
speedometer is accurate, as is the GPS position location. We've confirmed
that other similar models (of the same year) do NOT have this problem.
Basically, the dealer is clueless as to what to fix, as they've never seen
the problem and don't know what to do. So, they refuse to do anything.
The car's GPS system has this problem consistently. It's not
intermittent. You can put in a destination 60 miles away (for example),
proceed to drive 60 miles an hour, and it'll tell you that you're 1:18
away (instead of 1 hour).
Do any of you experts out there have a clue? TIA. Neall

Re: Accord GPS "time to destination" error
I don't have the built-in navigation system, but I use a GPS on the dash with a laptop computer. My system determines car speed and location strictly from the satellites, it has no connection with the car's components. I would expect the Accord to do the same, so I would look to upgrade the DVD software for a possible fix. On the other hand, if this error is so predictable, you have one of the easiest issues to overcome... Al

Maybe it discounts speed for traffic lights and such.
I wonder if (please excuse me) there's anything about this in the

The built-in navigation systems use the signal from the vehicle speed
sensor in addition to GPS. Most of them also use a gyroscope. This
provides for more robust navigation in areas where satellite view may be
spotty, like in tunnels, parking garages, and when you are surrounded by
tall buildings.

Re: Accord GPS "time to destination" error
Hmmm... don't buy that, the only way the navigation system knows where you
are, and how far you are from where you are going is with satellites.
Perhaps the Accord navi uses the vehicle speed connection, but that is not
more accurate than the speed determined from satellites, nor does it help
when satellites are not available because of obstructions... Al

And as an additional point, when I am descending down a multi story,
enclosed, concrete parking lot the system know exactly which way I am going
and accurately tracks my travel. I don't think satellite reception is all
that good. My Garmin handheld, for example, does not work in that same
environment.

I don't have a clue, but I will say that my Accord's estimated times
are right on, and even corrects itself while driving if going slower
or faster than normal. However, my dad's Toyota Prius seems to be off
in this regard. Turns out that, on his car, it simply uses three
different default speeds for all highway, surface street, etc. routes
(or something like that), and you can go in somewhere and adjust those
speeds to your liking and to match present-day driving realities. You
might have your friend dig into the NAV manual to see if that
adjustment is possible on Hondas as well.

I don't have a clue, but I will say that my Accord's estimated times
are right on, and even corrects itself while driving if going slower
or faster than normal. However, my dad's Toyota Prius seems to be off
in this regard. Turns out that, on his car, it simply uses three
different default speeds for all highway, surface street, etc. routes
(or something like that), and you can go in somewhere and adjust those
speeds to your liking and to match present-day driving realities. You
might have your friend dig into the NAV manual to see if that
adjustment is possible on Hondas as well.
