Okay, I am way confused with map update. It might be because I read a lot of the earlier posts which are now obsolete. I have a 755T and I downloaded the files that apply but I am not clear as to what/how I should use. The following are my questions:
Q1: Is there a limitation on the SD card size that can be used? I was going to use an 8 GB card but I am not sure my 755T will recognize.
Q2: I was hoping to put the update on an SD card so as not to affect my existing configuration. From the tutorials ([Only registered and activated users can see links. Click Here To Register...]), it appears that once I use the SD card, the unit will not work properly if I remove the SD card. Is this still true?
Q3: Some of the tutorials reference Basecamp, MapSource, MapInstall and HomePort. It is my understanding that some of these are no longer supported from some of the threads. For the unlocked images, can Windows Explrer simply be used? Someone with more experience may want to clarify the obsolescence issues upfront in some of the tutorials and indicate the current preffered method.
Q4: I took the original MapSource data and used one of the unlockers (NOTE that GarminUnlocker.exe which uses the .tdb file did not work for me) as Mapsource and MapInstall were saying it was locked (yeah duh, I realized that afterward). I ended up using MapInstall and put on my 8 GB SD Card. I see it created a single file (gmapsupp.img) and that's where the duh moment kicked in (unlocked map is already this file). I have not put SD card in my GPS yet. Could I have simply copied the unlocked gmapsupp.img file directly to my GPS? I don't currently have a gmapsupp.img file on this GPS and I don't think there would be enough space.
Q5: From the file structure of my GPS unit, it looks like the GMAP3D.IMG file goes in the Garmin subdirectory since it is already there. A quick check of my 755T does not show these files at all:
D3060070A.JCV
D3153070A.JCV
D3397050A.DB
D2656080A.SID
D3157060A.SID
D3398050A.SID
D3406050A.SID
0464H4AO.SRX
0464H4AO.ASR
How/where would I put these files?
Q6: From what I see, can I simply copy the gmapsupp.img and GMAP3D.IMG files to the Garmin directory using Windows Explorer and consider the update complete?
Sorry for my confusion, I may be overthinking things.
Lets keep it simple.... To update a 755 only 3 files are involved and they are a matched set with each release.Quote:

1. gmapprom.img the detailed maps
2. gmap3d.img the 3D buildings (this is optional for giving you 3D buildings view if enabled and it really slows down the drawing speeed on a 755
3. DxxxxxxxxA.JCV is the Junction view file, also optional. You will not see any junction view photos without it.
gmapprom.img and gmapsupp.img are interchangeable names. In other words you name/rename this file depending on where you use it.
gmap3d.img and gmap3d1.img are also interchangeble names. In other words you name/rename this file depending on where you use it.
To update a 755 internally you need these names and paths
x:\garmin\gmapprom.img your maps
x:\garmin\gmap3d.img your optional 3d buildings
x:\garmin\JCV\DxxxxxxxxA.jcv your optional junction view files
To update a 755 with the new maps on SD you need these names and paths
x:\garmin\gmapsupp.img your maps
x:\garmin\gmap3d1.img your optional 3d buildings
x:\garmin\JCV\DxxxxxxxxA.jcv your optional junction view files
Note... gmapprom.img, gmapsupp.img, gmap3d.img are files you would be downloaded. You may find LOCKED or UNLOCKED versions of these files. Download UNLOCKED copies if you can find them. If you get LOCKED files, download the "GImgUnlock.exe" tool and unlock them yourself.
Q1: Any Kingstone SDHC (4-8 class) card work well on my Nuvi 765 for example! The best value for the amount of 16Gb today. I of course have limitation in 4Gb for first and second map on card (8GB totally) but I need in addition space for 3D.IMG and JCV files and so picture and POI.
Q2: If you remove the SD card with maps of course maps in the device will not be! Nuvi work with only a memory card inserted into the device. If the card in your pocket is not serious to wait what Nuvi read it :)
Q3: Basecamp, MapSource, MapInstall and HomePort is actual program and work fine if you know what you want to do with its.
Q4: Stupid question because you have not done anything. Try and then ask!
Q5: Only JCV will work on your Nuvi. D3060070A.JCV is suit for you. But not at all intersections is in it. Be realistic!
Q6: If you do it as written in this forum so it is no doubt in success. Have problems - ask!
tiger555 and Giomen -
Thanks for your replies that really clears things up - I knew I was reading too much into this. That does leave me two last questions:
Q1: Windows Explorer - I know I can't view image file with it but can I use to drop and drag the img files to my GPS unit thus avoiding all Garmin tools?
Q2: With the .JCV file, I did see the JCV subdirectory and the name of the JCV file is different. Do I:
a) Copy in the new D3060070A.jcv file and leave the old one?
b) Copy in the new D3060070A.jcv file and delete the old one?
c) Delete the old one, copy in the new D3060070A.jcv file and rename to that of the old one?
- Thanks again -
One more thing... If you have multiple versions of a map installed, enable only one at a time. Otherwise, they will not work correctly. For example, if you have both "CNNA 2012.1" and "CNNA 2013.2" installed, select only one at a time because they cover overlapping geographical areas.Quote:

Works like a champ - thanks for the help!
I think this occurs automatically, personally verified with CNEU NT. If you mount a more recent version of the same Map (same Map family), this one overlay the older one, for the corrisponding coverages ;))Quote:

Although not really recommended, if it's the same map series the overlapping info usually isn't a problem even if the versions do differ. Last year i spent several weeks in northern NA, mostly in Wisconsin and other States bordering CA. Using an AU1350 with USA Lower 49 2012.20 and CA 2012.10 (which included the US northern border states) loaded on a microSD and didn't realise until later that both maps had been checked as selected on the unit (i blame my un-gps-savvy travelling companion for that). It does beg the question of what might have happened if we had just chanced to be some exact place where the map data had been updated in the 2012.20. If the unit was getting conflicting info from both maps, would the later version have 'automatically' overriden the older one because it's 'overlaying' it, as FireFox58 thinks, or could the nuvi have had a 'hissy fit'? Probably not something you want to find out in the negative if you're in the middle of an unfamiliar city during peak-hour or negotiating a busy freeway interchange. The safest policy would be, don't select both if you have maps overlapping and their IDs differ as it's pointless anyway. If both have the same version and family it doesn't matter at all.Quote:
