    Re: New Nuvi 50 purchased in USA. Can I install Europe maps?

    Have I wasted my money?
    Any advice on how I can install the 'ing' (I think you mean "IMG") maps I have found would be appreciated. Thanks.
    You haven't wasted any money.

    In your device the maps are probably in a hidden folder named ".system" and if you change your windows setting you will see them. Your pre installed maps are named gmapprom.img (all garming maps have the ".IMG" extension.

    Your 50 has limited memory you can do several things... Let's say you have downloaded a UK&ROI map. It's probably named "gmapsupp.img" and you can rename that file as required.

    1. if you want to replace your pre-installed maps, rename the gmapsupp.img to gmapprom.img and replace the existing file in the 50.
    x:\.system\gmapprom.img (that would essentially be a map update)

    2. if you want to put that UK&ROI map inside the GPS and have room (this would be an additional/supplemental) map
    - Rename gmapsupp.img to "UK and ROI.img" (or any name you'd like to use but it must use the .IMG extension)
    - create a folder in the root of your GPS named "Map" with a capital "M"
    - copy the map to the Map folder pf the GPS as
    x:\Map\UK and ROI.img (or whatever you have named it)

    3. if you want to put it on an SD or micro-SD it's like you did in step 2 but on the data card
    - Rename gmapsupp.img to "UK and Ireland.img" (or any name you like but use the .IMG extension)
    - create a folder in the root of your SD named "Map" with a capital "M"
    - copy the map to the Map folder on SD as
    x:\Map\UK and ROI.img (or whatever you have named it)

    Once you've done that the GPS should see it and it will show up on your map select screen for use.

    Re: nüvi 30/40/40LM/50/50LM

    Could not make it work in any of the ways suggested. The Nuvi 50 has no maps to view. When looking at the files on the system there is nothing
    to show for .img files in any of the folders. I have drilled down in all the folders and found nothing regarding maps. Not sure what to do next?
    Thanks for your help though.

    It does have lots of stuff... you must be doing something wrong. Perhaps not going into mass storage mode or not viewing hidden files and folsers from the PC. Take a look at this post and look through the tutorials.

    I can't give you any other advice as I don't have a Nuvi 50 to play with. Don't give up.

    You can always put multiple maps in a "Map" folder on an SD/MicroSD and leave the GPS alone.

    Re: City Navigator North America NT 2013.30

    I know its off topic but can anyone tell me if its possible to change the dashboard or even relocate it on the Nuvi 50? There has to be some hack to do this. I've seen other garmins that the dashboard was down on the bottom of the screen instead of taking up 1/4th of the screen on the right.

    Re: help needed for installation of australian map on nuvi 40 garmin device

    Under the well established KISS principle - leave the files in hidden Nuvi 40 directory ".system" alone. To accommodate the additional Australian map on the Nuvi you will have to:

    (1) create a new directory called "Map" in the Root Directory of the Nuvi 40

    (2) Rename the Australian map you have from "gmapsupp" to "Australia 2013.30" - presuming that it is the latest Australian map release.

    (3) Check that the renamed "Australia 2013.30" is unlocked. To unlock use Fast IMG Unlocker 2.1. If you want to keep it locked you will need to generate a supplementary UNL file with the name "Australia 2013.30.unl". Earlier posts in the Forum will explain what is required to create the UNL file. However, the KISS principle suggests the unlocked file is the better way to go.

    (4) Put the renamed "Australia 2013" image file map into the the new "Map" directory. If you are staying with the locked version of map you will need to place the the UNL file created in (3) above also into the "Map" directory.

    I have a Nuvi 50 on which the process described above works perfectly.

    Re: Lost .img

    The most important files on the new Nuvis are in folder called .System. This is a hidden folder so you will need to go to Folder Options in Windows and select the View tab.
    From the View Tab select to Show Hidden Files, Folders, and Drives and also uncheck Hide protected operating system files (recommended). You should then be able to see the .system folder.
