City Select Mexico for 76CSx

I have a Garmin GPSMap76CSx - I use this gps on both sides of the US-Mexico
border and have purchased City Select Mexico on micro SD card. I would like
to load both the Mesico and maps from the US (mapsource) on a 1gb micro Sd
card. The instructions on the City select say that loading Mapsource files
to the card will overwrite the data on the card. Does anyone know if these
iles can be copied and merged so that corssing the border does not mean
changing cards?

Thanks

On the pre-loaded SD and microSD cards, the unique serial number
embedded in the card is used to tell if the maps are on the card they
were sold on. If they are not, you will get an map unlock error during
startup of the GPS receiver and the mapping will not be seen. You'll
still see your basemap of course.

If Garmin did not do that, the maps could easily be copied to other
cards and freely distributed. As it is now, the card and maps are a
unique pairing, you have to have that particular card and that
particular map file to see the mapping.

So, in short, there is no way to copy the maps to another larger card.

If you contact Garmin about this, remind them that Mexico is part of
North America and that that mapping should be included in City Navigator
North America.

The amount of additional mapping on CS Mexico appears to be a pretty
small amount more than the major roads that are shown in CN NA. I think
it boils down to street level detail for Mexico City and Guadalajara and
little more. Has that been your experience? Someone asked about that
here recently.

It sounds like the maps on your card are a \garmin folder and in a file
named gmapsupp.img. That is the location and filename used for
supplemental map files uploaded to memory cards by the MapSource
products that come on CD or DVD. That would explain the warning on
overwriting.

Thanks for the Info -

I seem to find that there are more of the "backraods" especially in the
sierra that are included on the Mexico database. I do not go to Mexico City
or Guadalajara so I have not had a chance to check those out - BUT I would
not drive in Mexico City in any case.

Thanks for the help

Jim

Thanks for info Jim. Driving in Mexico City would probably be just like
driving in the San Fernando Valley. Maybe with a little less cursing in
English.

I'm a Mainer now but I was born in La La Land...
