CitiNav Europe on SD card: gmapsupp.img?
Mathias Koerber
It contains a folder F:\garmin which contains
gmapsupp.img
gmapsupp.unl
files.
Strangs, I thought these would be gmapprom files.
And why an unlock code on an SD card?
Anyway, I now have another image/UNL combination.
I want to know if I can add these as 'gmapprom.img/gmapprom.unl'
to this to get the second map onto the card?

You can try it, but it probably won't work as the unl is coded for that
particular card. If you search long enough you can find a way to do it.
Some have moved them onto a larger SD card so they can include MP3s and
photos as well as the map.

This sounds like a misunderstanding.
I have the normal SD card from Garmin, which contains
CityNav Europe NT 11. This seems be stored as
gmapsupp.img/unl
So far so good, I want to keep that map.
I now have another map, which I have an IMG/UNL file
for (with the UNL file containing an unlock code built
for my nuvi!)
Can I add that IMG/UNL as gmappprom.img/unl
onto the card, so that it is seen as the second map?(I tried, but so
far no luck).
I had actually expected the ROM card to be gmapprom and not gmapsupp!

The files named gmapsupp.img file are used by numerous Garmin GPS
receivers. The gmaupp.img files normally contain supplemental mapping
for a device that has a base map or preloaded mapping (often in a file
named gmappprom.img)in main memory.
When you buy a Garmin memory card with mapping preloaded to the card,
the mapping is normally in a gmapsupplimg file that is locked to the
unique hardware serial number that is embedded in the memory card at the
time of manufacture. And that mapping will not work if it is moved or
copied to any other card. There is a "hack" that will let you copy the
mapping to another card but I don't recall the details as to what it is
or where you can find it.

Not as it is intended to work by Garmin. Garmin's plan is that you can
have one memory card with supplemental mapping on it in a receiver, that
the mapping will be in a file named gmapsupp.img, and if it is mapping
that was sold preloaded to the card by Garmin the gmapsupp.img file must
be on the card that it was sold on originally.

That is not a ROM card, it is a supplemental memory card. I think you
are reading something into those file names that is not there. This is
all in an area where Garmin shares little or no information with
consumers. It is not anything that we need to know or that they intend
for you to do.
