Hi All,
A couple of months ago I bought the iBlue, and I Guidance software for the v51. It is a nice set-up and has helped me out a few times. But....
1. I tried to use it to go geocahing and the coordinates I entered were not accurate to the geocaches. Now I do not see a way to change these units anywhere on the ppc. Does anyone know what units the iGuidance is using and how to change them?
2. We were coming home from geocaching and I set the ppc to the shortest route and he set up his Quest for the same. The iGuidane gave me a distance of 14 miles but the Quest gave it as 15 miles. So we took the 14 mile route. However...(and you were probably expecting this, shorter took us over many slow back roads. How can I get both the shortest distance and the fastest route combo without going here and there?

Thanks for any help, bobolinx

Coordinates are in Longitude and Latitude. It may not be accurate because the GPS receivers have a limit on sensitivity.

You want fastest and shortest - no way to set it for both. Fastest is based on it's calculated time to travel, no matter the distance - usually using major roads with faster speed limits. Shortest is total distance, no matter the posted speed limits. Kind of hard to tell a computer to do both fastest and shortest don't you think?

iGuidance isn't the best for geocaching...I use Back Country Navigator...iGuidance doesn't respond well to being "off road".

I would agree that street navigation software is not the best for geocaching.

There are a couple of possible reasons for the position being off. Since the coordinates on geocaching.com are WGS84 and the GPS should be displaying WGS84, this should not be a factor. The next step is looking at the position format. The coordinates on geocaching.com are in degress, minutes and decimal minutes, or:

DD.MM.mmm

You may be putting these into a program that takes degrees, minutes, seconds, or:

DD.MM.SS

This can cause very large (in the geocaching world) discrepancies. If the formats are not the same, look for a format conversion tool on the internet (there are dozens) or simply convert by taking the decimal portion of the DD.MM.mmm (or the mmm part) and multiplying by 60. If you had 45º30.500, this will give you 45º30'30.000" (or 45 degrees, 30 minutes, 30.000 seconds).

Oh, one last thing. I don't use iGuidance, but if it has a "lock to road" feature, make sure you turn this off for geocaching as it will put your position on the nearest road even if you don't want it to.

Hope that helps. :)

iGuidance displays coords in decimal degrees only. You will need to convert to ddmmss as Greymane21 describes above.
