Help

I just bought a Lowrance Globalmap 3500C. the navigation charts for boating
is worthless for my purposes. What I want to do is to download their the
NOAA ENC chart for my area or the NOAA Raster chart, and then save it on a
MMC card (that my Globalmap can read) and use those charts instead.

Problem is, I am totally dumb on how to do it. I am aware that i can buy
these fancy packages from NAVTECH or NAVIONICs, but I just want the basic
NOAA type chart that can be the blackground map for my GPS...but as I said I
am totally dumb on how to do it. I do not believe that either the raster
charts or the ENC charts are in the correct format for the GLOBALMAP.

Any help (other than just go out and buy the NAVIONICs, etc.) would be
greatly appreicated.

As a general rule, the _only_ charts you can load into a consumer
mapping receiver are those provided by, or authorized by, the
manufacturer of that receiver - in other words, since you have a
Lowrance receiver, you can only use charts that Lowrance says you can
use. Likewise, if you had a Garmin receiver, you could only use
charts that Garmin recommends.

This was true at one time, but lately several people have made
topographic and routeable maps compatible with Garmin receivers...

For example there are third-party maps od Mexico:

Routeable maps of Colorado and other western states:

And I'm currently working with a fellow that is making marine charts for
Garmin receivers virtually the same as their BlueCharts...
