Garmin Nuvi 1450 / 1460

[silverbeauty]

Just discovered that /Map folder in the SD card works as well (so long as it is in the root directory i.e. at the same level as the /Garmin folder). I decided not to have any maps in the internal memory and moved all my maps to my 8GB SD card leaving only the JCV files and basemap in the Internal memory. I now have more than 10 maps in the card and still plenty of memory capacity left. All the maps are available for selection through Tools>System>Map>Info. Very neat feature.

NOTE: This is for those who wish to store multiple maps into the SD:/Garmin folder that will also have jcv and lane assist whose files are stored in the SD:/Garmin/jcv folder. AND also for the brave trying something that may possibly brick their unit

There is the GarminDevice.xml file in the main memory:/Garmin folder that determines what file names, path, I/O etc in the device. Notice that you can put maps in the SD:/map directory but the maps will NOT have jcv or lane-assist. This also for maps placed in the Main:/Garmin/map folders. Unfortunately, only a max of TWO maps at a time can currently use the jcv files and it must be named gmapsupp.img. placed in either of the /Garmin folders. POSSIBLE SOLUTION ??

Use a text editor and look at the GarminDevice.xml file: The NMaps xml format does not have a BaseName slot. Thus the SD:/map folders can take anyname.img. Now if you want to put multiple maps into the SD:/Garmin/ folders with anynames.img using the jcv files in your 8G SD:/Garmin/jcv folders here's what you do: Within the SupplementalMaps remove the <BaseName>gsuppmap</BaseName> characters in the xml file. Now the SD:/Garmin will be like the Nmaps, taking any names. You can now store all your unl files in SD:/Garmin with other multiple maps there and it will use the jcv feature. And you do not have to touch your main memory pre-installed files (except this file!!)
Anybody brave enough to try and come back from the dead? Just be v careful - remove only those characters above at the correct location and type carefully. Otherwise you have no device and the usb comms will fail!

Did anyone try this and works ? Means we can save multiple maps and multiple JCV under sd:/Garmin/ and sd:/Garmin/JCV and load them in 1460 ?

thanks

I usually use only one SD card for one country Map/JCV file at one time as SD card cheap

Realised that my basemap is version 4.0 instead of 5.0 as some mentioned here. Should I upgrade it ? How do I do it ?

Basemap file name is gmapbmap.img and is stored in hidden folder of MainMenu /system

Where do I get the v5 basemap ?

Google is your best friend

I tried, can only find basemap v5 for GarminXT

I uninstalled WinZip and the icon has changed to a little box with a .img extenstion. I had this copied to my SD card but my nuvi 1460 is unable to read it and it is not shown in the Settings,Map, Info section.
Grateful for further help.

have you created a folder "MAP" in your sdcard ?

all the "img' files must be parked in that folder

Maybe not entirely true (see other posts on this forum). Here is what works for my 1460:
SD:/Garmin/gmapsupp.img and gmapsupp.unl (if needed) for one country map
SD:/Garmin/jcv/ jcv file works for the country with gmapsupp.img file
SD:/map/ anyfilename.img but no jcv feature for a second country map
Other basemaps, etc that came with device in main flash memory .System directory

When you select one of your saved Favorites, you will be presented with a GO option and the map showing the location. You will notice in the dialogue bubble, there is an option to Press for More:

The Edit and Delete options will be available after you pressed the blue words.

After touching Press for More, this is what you will get:
