Is it possible to turn the WAAS feature on or off in a nuvi 660?

I don't believe so

I couldn't find that specific option within your user manual.

Seems so

according to Garmin

Quote:

If you have a Garmin nuvi 300 or 600 series device you will have the option to enable WAAS/EGNOS. Enabling WAAS/EGNOS on your nuvi 300 or 600 series unit may improve the accuracy to less than three meters on average.

To enable WAAS/EGNOS on your nuvi:

* Power the nuvi on
* Touch on the Spanner/Wrench icon from the main menu screen
* Touch System
* Touch Off next to WAAS/EGNOS
* Touch On
* Touch OK
WAAS/EGNOS will now be enabled on your device.

Note: Only the nuvi 300 and 600 series have the WAAS feature. All other nuvi models contain a high-sensitive GPS receiver that does not require the WAAS feature.

This tells how to turn it on, but one of the options seems to be "Off"

I Have WAAS OFF

Yes it is quite easy to turn WAas|EGNOS feature on or off following jgermann's instructions.

Pesonally I saw no improvement on my 660 so I leave it off since it does use slightly more battery power when running on battery.

You may want to look at the link below for more information on WAAS\EGNOS

Great info gentleman

Surprised though that wasn't included in the user manual.

Once again it just proves the wealth of knowledge on this site smile

Info is in manuals

The setting is discussed in manuals for nuvi 300 and 600 series, zumo 400 and 500 series and in Streetpilot manuals.

Many users do not know how to get a manual but should by following http://www.poi-factory.com/node/30393.

Over time, I have tried to download manuals for all of the "on-the-road" devices. I have a package called X1 Search that scans stuff on my computer and lets me do various searches. It found 23 unique Garmin manuals.

I looked at the 600 series manual and for some reason can't find the reference to the WAAS feature confused

I must also definitely be doing something wrong as when I follow your link I also can't find my units manual (2x5) along with many others ???

Any help you can provide would be much appreciated smile

P.S. It's Friday and yes it's been a very long, cold & hard week grin

When I read my 660 manual I too did not find the detailed information of how to turn WAAS On\OFF that jgermann's comprehensive instructions provided.

Regarding looking for a specific manual this is what I do.
On Garmin's Home Page, in the upper right hand corner, in the search box, I type in the model I'm looking for.
In your case Nuvi 255W. On the next page I click on that model. In that page in the right hand side you will see the option to download manuals. On that page you will find the owners manual as well as some others.

Here is the link for your 255W manual:

Thanks muell9k

I find your method efficient because you can find every manual out there whereas the other link provides just a handful of selective ones.

Moving along wink

First, let me say that what Muell9k suggested is exactly the way I download manuals. When I do this for the 600, I am told that there are no English manuals. However, when I do it for the 650, I get this address:
http://static.garmincdn.com/pumac/nuvi650_OwnersManual.pdf

Right now, I am hung up trying to download it

What I have on the computer - saved from when I downloaded it on 6/3/2010 - is a manual whose title page says
Garmin....................Owner's manual
..........nuvi 600/650

It was printed on March 2007
it is Part Number 190-00809-00-Rev.B
and was printed in Taiwan

My attempted download today was by clicking on the link at
http://support.garmin.com/support/manuals/manuals.htm?partNo...

While I am writing this in Chrome, I stopped my attempted download in Chrome and switched to Firefox to attempt a download because that browser has a download bar at the top of the screen. It has moved the bar a bit but still says it is on page 1 of 49. I do see that this page is exactly the same as the one on my hard drive.

Will let you know if I am successful.

You sound like you have a manual so this begs the question of why you cannot find WAAS. I did a search and there are seven instances.

Both links

There must be some internet squeeze between you and Garmin. Both links you provide download the full manual (under 1.8MB) for me in less than 5 seconds. WAAS is mentioned on pp 26,36,39 plus the index.

WAAS feature on Nuvi 660

What is WAAS?

Nuvi and WAAS

Somebody correct me if I am wrong (please) but doesn't the Nuvi line have "Lock on Street" function enabled? In that case having WAAS is a waste of computing power?

which was a good

reason to remove it. As WAAS is intended for aviation uses, it doesn't provide a truly appreciable increase in accuracy below 3,000 feet above ground level.

OK, now I understand more

OK, now I understand more about it....

Now a 2nd question.... So I'll only get more accurate positioning if I'm flying or on a road above 3000' above sea level?

Is this accurate?

has anyone with a Nuvi 660 or such noticed a speed improvement on complicated (Inner city) map drawings with it off???

WAAS is useful

First of all, I'm very much in favor of being able to disable things like WASS. Or even being able to exclude the Russian Glonass satellites or the USA GPS satellites on systems that support both (a feature that I have not yet seen in any GPS receiver). There can always be a failure or even a deliberately introduced error. Glonass has already suffered such a failure and the US could always turn back on "selective availability" or do something else similar.

However, I question the wisdom of disabling WAAS by default. First, I don't believe that saves any power. AFAIK the WAAS signal is on the same original frequency as the civilian GPS signal, and would be received by the same receiver, just at a slightly different time as the satellites step through their time slots. Additionally, WAAS isn't affected by the doppler shift that the GSP signals are, so a radio doesn't need to adjust its frequency to find the WAAS signal.

Overall WAAS could save power by helping a system lock in faster, particularly on a cold start.

WAAS compensates for propagation errors that affect the GSP signals as they pass through the atmosphere. The speed of light is a constant through a vacuum, but not through the atmosphere, it can be affected by temperature, pressure, moisture, and other related factors. It doesn't matter how "sensitive" you think your receiver is, these atmospheric factors can still affect your received signal and thus your computed location, When the WAAS error correction is minimal it might indeed seem that it wasn't needed when it is disabled, but other times when the atmosphere is different WASS can significantly improve the calculated location by providing the receiver with correction information over a large geographic area. Don't disable just because you can.

I decided to leave it on....

I decided to leave it on.... But as you know, I had OTHER ISSUES!

WAAS

Frovingslosh, thanks for your good info. I agree with it.

This is my opinion in a discussion with JanJ copied from another thread. JanJ had placed his nuvi 660 in an outside location because it had been relocated while turned off, and had turned WAAS off and then on again:

It is likely that when you turned off WAAS, the 660 lost the WAAS satellite almanac info. (Where the satellites are) When you turned WAAS on again it needs to download the almanac. It will scan successively through many satellites around the world, but it can only receive the WAAS almanac from one satellite in the southern sky.

If the outside location does not have an open field in the southern sky the nuvi will be using some battery power to keep scanning for the WAAS almanac without ever receiving it. Even a tree in the way could prevent this.

WAAS provides better accuracy for the 660, but if it cannot see the WAAS satellite, it will lose its position. That is why WAAS works better for airplanes or boats. In my opinion it was not a good idea for Garmin to equip a road GPS with WAAS. I would turn off WAAS for the 660, then put it outside to get its position. See whether it always has a good position in the future.

http://www.gpsinformation.org/dale/dgps.htm

At the above link, there is a map of the world with locations of the WAAS satellites. However, the map is not up-to-date. There is an edit in the text below the map.
