Maps and Garmin GPS map60CSx

Hi all,
Some time ago I asked a question concerning the greatest capacity micro SD
memory card I could use in my Garmin GPS map60CSx. The answer I obtained
from this site, after considerable discussion, was 2 gs. I have since bought
a card and I have bought topo maps for Australia and City Navigator. I now
have difficulty using them.
I have managed to unlock both. My problem is this. I can transfer maps from
each to my GPS, but each transfer seems to wipe out the preceding one. I
understood before I bought the unit that I could have both on the card and
not only swap between the two, but overlay one over the other. Can this be
done? If so, how do you get both sets of maps transferred to the card if the
second one always wipes out the first. I really find it hard to believe that
it would be made like that. I am using "mapsource" that came with City
Navigator NT.
Thanks, Dan

Hi Dan,

I have a 60Csx, and have both Metro v8 loaded and 1/3rd of Topo 2008, on a
4GB mSD, and switch between both. You need to select the map tile you want
from both of the mapsets from within Mapsource, and then use Mapsource to
load the img file to the mSD card. You will then be able to select within
the GPSr, which of the maps you want to display.

As I understand it, it is not possible to load separate img files (in
different folders) on the mSD, and select within the GPSr. The GPSr sees
only one img file in the Garmin folder. Anyone correct me if I'm wrong.

Cheers Buddy!
Jim

That is exactly how it works. There is a \garmin folder off of the root
of the card, that contains a file gmapsupp.img, and that is the only
location and filename that the software on the 60CSx will use. And the
MapSource Transfer menu does not give you any options for changing the
destination folder or filename.



All the different optional or supplemental MapSource mapping products
perform the same as far us described above. There are some variations
on overlaying some maps over another. For North American mapping, you
can only view or use one mapping product at a time. There is also a
"Marine Points Database" with marine aid to navigation that can be seen
with (overlayed on?) other mapping products but only one mapping at a
time can be seen.

The Garmin UK topo apparently displays over the basemap and maybe even
other mapping products. Your supplemental mapping may do that too.
U.S. Topo does not, I have to turn off City Navigator and BlueChart maps
I have on the card to see the topo maps.

I can leave the Basemap and the Marine Points Database on all the time,
the Basemap does not add any detail to other maps, as far as I have
noticed anyway,

There is a hierarchy for display of maps when you have more than one
type of map turned on from the Map Info menu and the un-named sub menu
from there for controlling map display.

Map Setup - Information icon, and you'll see the name of one of the
individual maps from one of the map products in your gmapsupp.img file
there.

Cursoring down will let you check and uncheck (turn on and off for
display) the individual maps (these are the individual maps or segments
as you selected them in MapSource) but it is faster to press the Menu
key again and use the Show and Hide choices to turn the maps from each
product on and off as a group.


In MapSource, select the maps from one product (only one can be viewed
at a time), then choose to view the maps from another product and
continue selecting to add them to the list. The selections are listed
on the maps tab, clicking on the Name column will resort them and group
them by product, and at the bottom is a summary of the number of maps
selected and the total size of the selection. The limitations are that
you cannot select a total of more than 2,025 maps and, or course, you
cannot exceed the size of your memory card.

When you transfer the map it will be a little larger than the size seen
in MapSource.

Once a map is transferred to a card it can saved back to your PC and
copied back and forth from the card to the PC to change the mapping file
on the 60CSx. You'll see a short delay at the first startup each time
you change map files as the GPS reads the map file. As long as the map
file is the same, it will not re-read the file on subsequent startups.

The business of storing multiple gmapsupp.img files boils down to you
using the basic DOS operations on directories and subdirectories (i.e.,
folders and sub folders) and/or naming and renaming either files and/or
dirs and subdirs so that the GPS software sees the map file you want it
to see at startup.

Until you have mapping that exceeds the 2,025 maps (as selected in
MapSource), it is generally easiest to simply combine all the maps into
one file and manage which one you see and use from the GPS.
