Adding multiple maps in Garmin Nuvi GPS

About Garmin maps Additions files (gmap3d-JCV-gmaptz-ASR-G2S))

Thx PietU but... my answer have more complexity of your interesting sticky thread.

To use the junction view files, drag the entire “JCV” folder into your “Garmin” folder.( x:\Garmin\JCV )
folder.( x:\Garmin\JCV )[color="seagreen"]or[/color]
JCV in a subfolder called JCV on the SD Card

JVC : folder.( ZUMO:\Garmin\JCV ) or [ONLY] [color="red"]or[/color]/[color="blue"]and[/color] [mem/SDCARD] also?

same answer on [color="red"]gmap3d.img[/color] in [color="blue"]/Garmin[/color] folder of internal Memory.. it's possible other one simultaneusly on [color="blue"]/Garmin[/color] folder of [color="red"]SDCARD[/color]?


for MAPS teorically..
four on internal memory

* gmapbmap.img - the default base map
* gmapprom.img - the primary mapset
* gmapprom1.img - the secondary mapset
* gmapoem.img - the OEM mapset that cannot be unselect by user (if it exist)

and other one ONLY maps on SDCARD:
* gmapsupp.img - the supplemental mapset which you can have one in the attached SD card.

I have lots of maps on my device all working perfectly...

i can just disable the ones i don't use in the setup > map > map info / select map

my oregon 450t has the latest official software update

I have 16GB class 10 microSDHC cost me £20 and is working perfectly :D

i just name my maps with names that i can identify easily

DISCOGB50K.IMG <---Discovery GB 50K
DISCOGB50K.UNL
TOPOGB2.IMG <---- Topo GB v2
TOPOGB2.UNL
TOPOPL.IMG <---- Topo Poland 2011
TOPOPL.UNL
TPDGB25K.IMG <---- Thames Path Discover GB 25k
TPDGB25K.UNL

I am sure i can just keep adding maps to my SD card in the GARMIN folder and they will all work :D

yes, new device/firmwares eg. 1.xxxx series can use \map directory also and any name for image
old nuvi series and mobile XT & PC can use only garmin folder and couple names what is given in tutorial section

[color="sienna"]There is no general answer that works for each device, just need to try and wrote in this forum info about the experiences of various devices[/color]

This has been a great help. I have just updated the firmware on my Oregon 400c and put in an 8GB Micro SD. I have loaded and renamed several *.img files on the card. They all load and are listed to en- or disable.
Other advantages of the firmware upgrade - a Man Overboard button (I sail), waypoint averaging and "sight'n'go" which is great for staying on course when not actually navigating to a waypoint.

Keep up the good work
