Multiple maps on SD Card

@MSigol
You haven't said what unit you have, but this is universal: In sd root, create a folder named Garmin. Inside copy the unlocked Bluechart named as gmapsupp.img i.e. x:\Garmin\gmapsupp.img is the path. Also see catymag's post above yours.

Don't bother to try to use MapSource when working with Bluecharts. It can be done but it's a pain in the butt and near useless anyway. HomePort is the correct program for Bluecharts. It will see them on an sd card regardless of their name (i.e. you can chose any name: AnyConvienientName.img), in a folder named Map as well as the Garmin folder. It will even see the images if still locked.

By the way, later, Can I sync with mapsource? or need to install tha maps from cero?

Big question with small info!!! Device??? Format of BlueChart (old version for MapSourse or new IMG format)??? Please, be more specific in question! Garmin have so many different devices and maps...

Dear All / Catymag,
On my Nuvi 3450, I create folder SD Card\Map and place the .img map on the folder.
However the map cannot read/detect.
I try to create on SD Card\Garmin\Map give the same result.

Is there any trick how to put maps in storage card for Nuvi 3450 ?

TIA

SD/Map is ok. But is the map unlocked ? Have you named the map anyname.img (example CNA2013.30.img).
In Map folder gmapsupp.img name is not supported.
look here [Only registered and activated users can see links. ] 37xx is the same than 34/35xx

I already unlock the maps by using gimgunlock 0.3 and
I already rename the map , just like CNI2012.img , NavigasiMap.img
and I put freemaps on SD\Map but still cannot read.

I notice SD\Garmin\gmapsupp.img --> this map can read

I wonder maybe we have to put the maps in other location/folder ?

Thanks and regards

My config:

Device:
System\gmapprom + gmapprom1

Flash:
\map\gmapsupp + gmapsup2

In new Nuvis is "Map" not "map"- This folder supports anyname.img, not sure it supports gmapsupp.img. You can use gmapsupp.img naming in sd/Garmin, but just one gmapsupp.img per Garmin folder
