Nuvi 660 - Altitude

bump

The altitude is displayed on the screen that shows the connected satellites (click on the satellite scale on the main screen).

Thank you very much.

I saw your reply to a question about altitude. When I go to the satelite screen, I see 0.0 in the upper left corner of the screen, and another number (right now, 425) in the upper right corner of the screen. Can you tell me what these numbers mean, and how they relate to altitude. Thanks.

the number on the upper left of the screen is your ground speed if you're moving. If you're still, it will be 0.0 The number on the right is your elevation, and the numbers bottom left are your present coordinates.

Thanks

On my 750, all you have to do is to touch the car and it will show your lat and long, altitude, nearest address and nearest intersection.

all consumer GPS models have problems giving a consistent, accurate altitude reading. Lat and Lon are rather accurate, when you consider what the unit is really doing. Altitude is usually off by considerably more and my units have trouble even decide what altitude it thinks is correct.

While stationary, with a clear sky, the altitude reading fluctuates considerably vs lat/lon and frequently is off when compared to the known altitude. But, it gives a general idea.

lat and long can be thought of as fairly ideal units, referenced to arbitrary designation on a sphere.

Altitude is a whole 'nother kettle of fish -- it's an offset from a reference (calculated) oblate spheroid. That spheroid is an approximation, and as an approximation, it's bound to be better in some places than others.

cheers--
