Deleting Maps

[pavejon]

I looked around at different forums but haven't found the answer I need. I loaded some maps onto the Garmin to test out the GPS feature. Which file do I delete from the Garmin to delete the maps I installed?

I have the Filez program so I can locate the files on the Garmin and my storage card.

There are typically two files that contain the map images. GMAPBMAP.img is the base map. gmapsupp.img is the detailed map. Both are located on the SD card under the garmin directory. You may also have a grmn_log.txt file. I believe this is the track log file but don't hold me to it.

The base map file may not be on the sd card and maybe on the handheld.

I wouldn't worry about deleting the detailed map file unless you simply want space on the SD card. The next time you create a detailed map file and transfer it to the card - it should be overwritten. This file name does not change - it's constant - which is how the Que knows which maps to display in detail views.

If the maps are loaded on the iQue internal memory, they are labeled differently from the files on the SD card.

GMAPBMAP.PDB - basemap in internal mamory

GMAPSUPP.PDB - small detailed maps in internal memory

GMAPBMAP.IMG - basemap on SD card

GMAPSUPP.IMG - detailed map on SD card

Note that Garmin SW is sensitive to case - it expects to see the caps!

What happens if you move a basemap with filez to card, won't it work then or do you have to change the extension?

Before the Update 2 - I tried this and it wouldn't work. Base map had to be loaded through the install CD. And I'd bet there is no reason to believe that this has changed. But I'm not in a position to try it at the moment.

[Robertp366]

Sigh! When I tried to move files as you suggest, I ended up with a lot of problems - in fact, that's how I learned about the importance of folders, naming, caps, and extensions.

The basemap and detailed maps don't work if not exactly the right format for the storage location they are in! .PDB for internal storage, and .IMG for SD card storage. I am not sure if just changing the extension is sufficient tol make them work after moving them (never tried, I just reloaded from backups I had).

BTW the maps must be in a folder named GARMIN (caps important) on the SD card.

Generally, the SD card must have 3 folders - AUDIO, PALM, and GARMIN. Inside PALM also are two folders named Launcher and Programs. And just in cast you think this makes sense, programs that run from the SD card must be in the Launcher folder, not the Programs folder!

And store your mp3's in AUDIO. The iQue will also store voice recording WAV files in this folder.

I loaded the worldmap basemap 30 MB to sd card via card reader through mapsource, it got named .img allright and works fine.

The GMAPBMAP.IMG file is 31440 something while
the GMAPSUPP.IMG is 39456 something and
the NonVol.bin id 1k

Actually, this is wrong. My detailed map file is not 39 megabytes but 394 megabytes, Filez doesn't report a file that large correctly.

I wrote "something" because there are no units specified on the two larger files.

BTW it is not a genral rule that map pdb files should be in RAM. I have about 10 MB of London street maps and underground froom Tube LOndon Streets by visualit.co.uk in PALM/LAUNCHER while the single 86 K .prc file resides in RAM. Launcher rapidly becomes messy, since there is'nt any option to use subfolders if programs in rRAM should find their databases.

P.S. PALM/PROGRAMS seems to contain things like stored jpg's from flash photo etc that got installed via Palm desktop tools.

As part of the process of placing an img file on the SD card, a small pointer pdb (of the same name) file is created and placed in internal memory. That is why just changing the extension and moving the files to the card won't work; you don't have the pointer file in internal memory.

Now I don't know this from the documentation, I have inferred it from observation of the files as I have placed maps in the internal memory and on the card using the install tool and hotsync, but I'm pretty sure this is the way it works.

Thanks ique-denver, I wondered what the "little" file was but just figured I'd leave well enough alone. ;)

[Robertp366]

Actually, the small files are created in the location the files themselves are stored.

That is, on my SD card in GARMIN is:

._GMAPBMAP.IMG <1 k
._GMAPSUPP.IMG 50 k
.DS_Store 6 k
GMAPBMAP.IMG 31440 k (full world baqsemap)
GMAPSUPP.IMG 203584 k (my detailed maps)

The ._xxxxx files look like catalog/directory files to me.

On the internal memory I have:

GMAPBMAP 5235 k (the US lite basemap)
and NO supplimental file of anything close in name.

Furthurmore, When I loaded the SD card via my card reader, I only copied the large GMAPBMAP.IMG and GMAPSUPP.IMG files. The others DID NOT EXIST until I used the card in the iQue. The others were created by the iQue when accessing the map files.

Robert

[Robertp366]

BTW - The iQue will work fine with no map files in the internal memory. In the MAP app display, an option is available on the drop down menu to delete internal or SD basemaps and suppliment maps.

I keep the US lite basemap (5235 K) and a small local detailed map (1920 K) in internal memory so I can use the mapping and GPS capabilities even when I take out the SD card with map files and replace it with another Sd card - for photos, mp3's, ebooks, etc.

Robertp366,

Did you have the small files in internal memory when you loaded the SD card with the large ones?

As I stated before Update 2, I tried to transfer and couldn't get it to work but I'm wondering if the files are on the Que if they will "assist" in the transfer from or to the Card.

We are probably beating a dead horse here since the original Post has been answered about XX times but I'm just curious.

I may have to "play" again since Update 2 is out and I haven't tried moving img files back and forth.

I like your idea of the small base map and small detailed map on the unit - mind if I copy the idea? ;)

[Robertp366]

I continue to research these little files, and I think I know what they are!

I captured and disassembled the little files. Mostly cryptic hex code ( I just scanned them, I haven't yet tried to decode them). They changed each time I moved around in the map!

They must be pointer files for where in the .IMG files the current display page is!!!

Since my iQue is using the base and supp fules from the SD card, perhaps it never references the small basemap or supp file in internal memory. Hence, the iQue never creates the pointer files in my internal memory.

OOPS. I just tried that experiment - remove the SD card and use the internal map files. Still find none of the small "pointer" files. But I still think they are doing that function for the SD card map files.

Note: I am using the program SuperUtility to search these files. I do not find filez to be as complete. Of course, filez is free and Super Utility is comercial.....

You are welcome to use any of my good ideas.

You are also welcome to use any of my bad ideas too.

We can negotiate over the mediocre ones.

I'll start the bidding at ......... :D

The grmn_log.txt file was mentioned in the second post in this thread.
It's not the track log file, but a log file with CPU register dumps, created when the unit does a reset (and perhaps at other times too).

Actually, if you only want to delete base maps or detailed maps, all you have to do is go to the QueMap program, choose menu softkey (the one with an arrow pointing down) and a 'delete' option shows up at the top. From the delete tab, choose which map you want to delete.

I am back after a long time looking for help!!!

I rebuilt my home PC and so reinstalled iQue and mapsource. Prior to doing the maps I had changed the voice and hotsynced my iQue. This resulted in all my calendar and contacts coming into the Palm desktop. Until now all was fine. Now I selected the world map as basemap and regenerated the detailed map file. When I hotsynced now, it didn't come out of hotsync even after 1 hour. So, I cancelled the operation. I found that it had loaded the new basemap. On checking the SD card (512mb Panasonic), I can see that the GMAPSUPP.IMG file is there in the GARMIN directory. But, on the map the details don't show up. I tried copying the map file using a card reader. It copied, but iQue still doesn't recognise it.

Any suggestions ?

[apersson850]

The detailed maps are enabled in GPS - Preferences?

[ssaibal]

It actually worked. It took 70 minutes to download 250mb of detailed maps. Earlier I was not waiting long enough. Interestingly, direct copying of the GMAPSUPP.IMG file to the SD card using a card reader somehow doesn't let iQue know that a detailed map file is present on the sd card. Do we need to copy some other file as well ?

Yes, the detailed maps were enabled in the GPS-Preferences.

[apersson850]

Don't know, but if I look in the data records in the nonvol memory, using NonVolUtil, I can see that there are records like:

MDB Basemap Enable
MDB Map DB Record File Info
MDB Map List
MDB Map Status Data
MDB Supplemental Map Enable
MDB Supplemental Map Present
MDB User Defined Feature List
MDB Waypoint

At least some of these have names that indicate that they have something to do with keeping track of which detailed maps are loaded.

[Robertp366]

Copying the detailed maps directly to the SD card works fine, but you must be careful of the directory or folder structure for the Que to recognize the maps. Check a few other threads for details - I wrote it out once. Or reply and I'll find it in another thread.

Robert

[jonasolof]

GARMIN/ and then maps

GMAPBMAP.IMG for basemap
GMAPSUPP.IMG for detailed

All names in CAPITAL letters

That is, in the Garmin directory there isn't any subdirectories.

If one doesn't have 3rd party utils such as Filez, how does one see what is on the card.

On the main menu, there is a card info, but it just says that it takes up xx space of the total.

It doesn't give file names - or am I doing something wrong?

Is there a way to see the files without a 3rd party util?

[apollo 8]

Try fileman. This is a windows like copy ,move, delete utility for the ique. It only cost $10 try it for free.
