GPS Search By Coordinates

[chilibit]

Lat and Long take the form xx xx.xxx and this specifies a point in space.

The navigation system in my 2013 will not (seemingly) permit you to enter the entire string which you need for accuracy. It only allows xx xx.x and truncates the final two digits. Is mine misbehaving?

Another question: There is a tire change calibration function in the navigation system. It supposedly adjusts odometer readout (and implicitly mpg calculations) for changes incurred by tire sets of different circumference. So on a level road the calibration would sync odometer distance to the gps calculated value. Slick --- if I have this notion correct. What have you seen?

It is my understanding that the tire change calibration is entirely internal to the GPS - it has absolutely no effect on the odometer, mpg calcs, speedometer, etc. It is designed to assure that the "Dead Reckoning" function of the GPS, i.e. the distance the GPS estimates it has covered when it loses GPS signal (e.g. in a long tunnel, etc.), is displayed correctly on the map.

On my 2013, the coordinate format the system accepts is XXX* XX' XX" - whole degrees, whole minutes and whole seconds - no decimal values.

I wish it did accept decimal degrees like every government agency, police department, fire department, emergency services, etc., but it does not.

You can enter the full coordinate value, it just has to be in the format degrees, minutes, seconds.

What you are saying WRT calibration does conform to the words in the manual and makes sense. Some wishful thinking on my part. Once you say it I do recall reading it somewhere previously but my search parameter selection was insufficient.

On Lat/Long: If I use Garmin's Base Camp and ID coordinates it comes back N dd mm.xxxx I guess that is minutes and I convert to seconds by multiplying the .xxx times 60? So, for example, N35 50.984 becomes 35 50 59 in degrees, minutes and seconds?

Thanks again gaijin.

By Jove, I think you've got it

And, you're very welcome - always glad to help

That is correct. There is also the functionality in Garmin GPS machines as well as their their software (BaseCamp, etc.) to change the Lat Lno display from dd mm.xxx to dd mm ss as well as the ability to convert between datums (yes that is not correct Latin) ...

Ah, easy switch in BaseCamp. Thanks. Although the conversion is easy enough in your head once you understand the formatting. Latin plurals are often mangled. The new Science channel about Stripping the Cosmos is full of errors of exactly that nature. Thanks Elkaholic.

Yeah .. three years of Latin killed me in Dendrology. In general, the folks who came up with the genus and species names for trees did not know Latin and the gender and singular/plural of the genus and species are all messed up ....
