Is there a way to delete the current maps and reinstall a complete new set?
What map do you now have and what are you trying to install instead?
Whatever you plan, I hope you have a full backup of your nuvi's files stored on a hard drive, recordable DVD, etc.
When I look under map info it shows 2 set..I guess because I only upgraded a portion of the map...I brought this up in another thread..when I plot a course it always comes back with the address listed twice..I thought it could be the sd card but nothings on it and it does it even when the cards out. If I put upgraded maps on the card..how does the device know to use the sd card map and not the ones on the unit..thanks,Tom
You just could have posed the question on your original thread.
@muell9k: He likely thought it was different enough from his original topic that it merited a new thread.
@ the OP: if both maps have identical coverage in select areas that could cause your issue. When you upgraded the map, did you use Garmin's updater? What are the two maps? Check under Tools/Wrench > Settings > Map and select info. The version numbers should be displayed for each map.
Well I used Garmin MapInstall,,today I installed maps onto the sd card and heres what it shows as liosted...CN North America 2012.20..Nortwest Terr..Canada, CN North America 2012.30..Baltimore,Md(where I live) and CN North America 2012.10 US and Canada East.
Well now, that explains much. You have three different maps on your device:
2012.10 (United States, Eastern Canada)
2012.30 (Baltimore, MD)
2012.30 coverage overlaps with 2012.10. 2012.20 overlaps 2012.10. That is why you have duplicate POI entries whenever you search. It's pulling up the POIs from all maps that are in the area. You need to clean up your maps to fix your problem. The easiest way to do that is to move all your existing maps off the device onto your computer's hard drive and start over.
Using MapInstall you need to select the full extent of 2012.30, then you need to switch to 2012.20 using the drop down box in MapInstall and select the areas that are NOT covered by 2012.30. If you still have areas not covered by the combination of 2012.30 and 2012.20 then select 2012.10 in MapInstall, again selecting the areas that are NOT covered by the newer maps. Transfer the whole thing to the nüvi and you're done.
Based upon what you provided me, your 2012.10 and .20 maps have full coverage of North America and the 2012.30 map is a CityXplorer map. Am I correct?
No I dont have any city explorer maps...I tried to just update the whole device but it says not enough room so I have to put maps on the sd. I only selected the area I use everyday, Baltimore, to put on the device.I thought this would overwrite the previous maps when an update was done..how do I move all the maps to the hd...what are the map files called?
Nothing else works connect your Garmin to your PC and manually delete the maps then install the current maps.
@lamplighter1: You need to move unused voices off the internal memory onto your hard drive to provide enough room to install 2012.30 in its entirety onto the internal memory. However, while that helps you now, it won't help come 2013.10 at latest.
Since you are familiar with MapInstall and seem to realize you can't let Garmin's automated program do the work for you, you've got it easy. You simply select the SD card in MapInstall instead of the internal memory and drop portions of the map onto the SD card. What portions you want on the SD card is a matter of preference, but an easy way to split the map is to put the US on internal memory and put Canada on the SD.
You can of course put the entire map on the SD card, but if you go that route make sure you keep an old map in internal memory to prevent the nüvi from complaining about no detail maps. Deselect the map in internal memory afterward using the map info screen in Wrench > Settings > Map. Otherwise you'll get the duplicate POI problem again.
@lewc: I already covered that with lamplighter. As you can see, while cleaning up the mess on his nüvi is important, the reason he was having issues is just as important.
I have a similar problem with my 1490. First I backed up the SD card and my Nuvi. Then I reformatted the card to FAT32. With my unit connected to the pc, I deleted the gmapsupp.img file. Using MapInstall, I selected the lower 48 and a few provinces.
On my unit, I then copied my large JCV file back to the SD card L:\Garmin\JCV. The process took about an hour.
What are the map files name and what is the .jcv files?
On your unit, the map file name is gmapsupp.img. It does not matter what the map file name is called when it is displayed on your PC. The MapInstall Wizard will load the newest map that you downloaded from Garmin...
..Your unit does not support the JunCtionView,(JCV)
Bob, if he has more than one map installed on his PC, which seems to be the case, there is a drop-down box on the map screen in MapInstall that allows him to select the map of his choice. Using that drop-down box, he could for example take North America and Europe, select all the areas on both maps, and transfer them to the nüvi as ONE gmapsupp.img.
In any event, that's a bit peripheral to the actual issue lamplighter 1 is having.
I see the dropdown box now. I was just looking at his original post. And if he first deleted the maps on the SD card and the Nuvi, all his problems would go away.
Ok thanks..I did remove the voices I dont use..in the future if I just want to update on area of the maps..wont this just overwrite the map area I choose so I dont have 2 maps showing or do I need to update ALL the map areas?
in the future if I just want to update on area of the maps..
I am unsure why one would want to update only part of a map. Would you explain what caused you to pursue this course of action? Maybe, I am missing something I should consider.
The unit would not take a complete upgrade..it stated not enough room and at the time I did not have a sd card
so just updated what I needed. If I have this right I can delete my sd card, delete the map file on the unit then reinstall using mapinstall and I will have a set of fresh maps...right?
...in the future if I just want to update on area of the maps...
Let's say you got the whole of 2012.30 installed on your device. 2012.40 comes out and you want to update Baltimore only. When you run MapInstall it will dutifully create the new GMAPSUPP.IMG and overwrite the old one. The end result is a GMAPSUPP.IMG file with Baltimore in it and nothing else.
If you send the Baltimore map from 2012.40 to your SD card instead of the internal memory, you will have overlapping coverage in the Baltimore area and thus will have the duplicate POI issue again. Unless the maps are specially designed, such as the CityXplorer maps, you cannot have overlapping coverage on two maps.
While it's not a good idea given the host of changes that occur between map updates, should you want to update only a particular portion of a map, such as Baltimore for example, you will need to plan ahead. You will need to create two maps using MapInstall. The first map has the total coverage area except for Baltimore. This map gets renamed GMAPPROM.IMG. Then you go back into MapInstall and create the second map, consisting of JUST Baltimore. This map will be remain GMAPSUPP.IMG. Then whenever the map gets updated you can simply use MapInstall, create a new Baltimore map, and have it overwrite the old one.
Personally that's just too much effort for too little gain. Update the entire map and be done with it.
Thanks a bunch..that explains alot..I think now I can get this corrected
How does one delete the maps that are in MapInstall that are no longer needed..Id like to delete the files off the computer that are no longer needed
on Start menu: Uninstall Unwanted Apps: Garmin City Navigator
Windows XP: Start > Control Panel > Add & Remove Programs.
Windows Vista, Windows 7: Start Orb > Control Panel > Programs & Features.
For both, select the map you wish to remove and click on "Uninstall" to remove it.
I dont want to delete the whole program..in the drop down list it will have old to newer maps that were downloaded..how to I just delete the maps that are not longer current.
Each map update will show up as a separate "program" when you go to "Add/Remove Programs".
Uninstalling it is the only way to "delete the old maps" from the computer.
Ok thanks..will take a look when I get home
Well I got a chance to fool with this..I deleted the gmapsupp files from the sd and the unit..even tho the map folder was empty when I turned the unit on it still had maps 2012.10..dont know how but its there. Anyway added 2012.30 and 2 maps showed up so I deselected the 2012.10 and now its working normal.
Now my question is why do I still have maps showing when I deleted the contents of the map folder. Looks like 2012.10 will always be there..
hope I make sense??
You likely renamed a map file at some point. Search the nüvi using Windows Explorer for any file named *.IMG and remove all of them except the following:
The first is the basemap. The second is the time zone map.
Ok found them..I did have another one named gmapprom..will move this out and then from now on will remove the gmapsupp when I update. Gmaptz and gmapbmap will always stay..correct?
They stay always.
Ok..I think I finally got it..gsheeh..hows the average person suppose to update their units if there're not computer savvy?
Funny those files are located in a system folder which I cant even see if unhide hidden folders???
You learn on forums like this one.
Remaining ignorant is never an option. This is the reality of life.
Make sure 'Hide protected operating system files' is unchecked as well.
Thanks..learning again..so much knowledge
