2014.30 SID Files

On my 2460 with 2014.30 full North America, I only have ONE Sid file.
It is named D2656130A.sid at 503,230KB.
If this is the same file you show, then it's the correct .sid file for your newly downloade map.

Previous version (backed up) 2014.20 was D2656120A.sid at 488,129KB.

Not positive, but it's possible your 259MB file is the original SID file for the map version you received when you bought the unit. I believe it should have been replaced with a map update and not saved.

Here's a link that explains what SID files are.
http://www.pois-gps.com.ar/?page_id=2552/garmin/garmin-units...

I looked directly into the SID directory and found 1 more file ... (my original search was too high.)

D4954010A.sid 259,680 KB 20/11/2013 6:18PM
D3406100A.sid 126,523 KB 20/11/2013 6:16PM
D2656130A.sid 503,230 KB 20/11/2013 6:12PM

Interestingly enough, an old backup also contained the second file with a slightly different name (D3406070A) and smaller size. The D4954xxxx is new.

While your link gives great info, I believe the naming conventions of these files also pertain to something more specific.

It appears the update even bothered to update these files individually/sequentially.

I think this requires more research before I backup and remove these files from the SID directory.

A huntin we will go .....

.

Looking at the date stamp it appears all 3 files were downloaded with your 2014.30 map update.

My 2460 functions properly with only the one D2656130A.sid 503,230KB. I can't imagine your 2555 would require 2 additional files.
I believe the different file names indicate different map versions.

I'm curious, did you use MapUpdater or Garmin Express to update the map? I used MapUpdater.

If I were you I would backup the other 2 files to my PC and then delete them from the Nuvi. If it functions properly that would indicate they're not needed and taking up space.

Before deleting, maybe best to wait for somebody else with a 2555 that has 2014.30 can check their Sid folder and see how many files are present.

My 2595 has always had 3 SID files. I've used MapUpdater for all map updates:

Looks like the 25XX series does have THREE .sid files, so DON”T delete any.

I’m even more confused now. The only difference I can see between a 2555LMT & 2595LMT is that the 2595 has Voice Command. Both units come with the same full North America map.
Having voice command adds an ASR folder on the 2595 where the 2555 should not have one.

Why the different .sid files for the same series using the same map.

I'll be following this thread. Hopefully someone comes up with an explanation. My 2797 has 4 SID files.

After the latest map download, my free space is in the red. I would like to remove the old map files but I can't tell which are the old map files on my Nuvi 765t. Is there a way to figure it out.

If you did a standard map update (GarminMapUpdater or Garmin Express as opposed to the "clone"* method), your old map files will be replaced by the new version files and no old files remain unless you previously used MapInstall from your computer to install a supplemental map**.

The good news is that your 765t is a model that will automatically be offered a map update to a SD card if the update process determines that the largest map your device is entitled to receive will no longer fit in the nuvi's internal storage:

https://support.garmin.com/support/searchSupport/case.faces?...

An 8 or 4GB SD card may be in your 765t's future.

I expect that you could force the SD installation earlier by loading the nuvi with lots of jpg or mp3 files, then do the map update where the update process will determine the SD option needs to be invoked.

Once your map is on the SD card, the free space in the nuvi will increase tremendously since the very large map and jcv file will be on the SD card. Just remember that at this point, the SD card is part of the nuvi, and removing the SD card will remove your City Navigator.

**Supplemental maps will be left behind when doing a map update. This means that when doing a past map update, if you were forced to choose a subset of North America (e.g., Lower 48 states) to be installed to the nuvi--and you then used MapInstall to install Canada/Alaska as a supplemental map, you will need to manually delete the supplemental files. If this sounds like something you've done, shout back and we'll find the files to delete. As always, before deleting, moving, or renaming any nuvi files, please have a full nuvi backup made and stored on your computer.

This is a learning experience for me. These newer units have so many more files than the old ones, I donn't know what functions many of these new files are for.

I have taken the liberty of taking the three different units and composing the files in the same order to make comparison easier. Member NachoB’s 2795LMT also has full North America but has a 7” screen, the 2555 and 2595’s have a 5” screen. Regardless of the differences, the SID files use a large portion of internal memory.

And, even odder, our nuvi 2460 GPS models, both of which have had multiple map updates to date, have a single SID file of the size you reported earlier.

I wonder if there's a difference between the nuvi 2xx0 and 2xx5 series in this regard. It'll be interesting to watch the 2xx5 users reports after the next map update--as well as users of other newer nuvi models (the xxx7 comes to mind). If a new SID arrives with each map, it does beg the question of why earlier SID files are not deleted when the map is updated as occurs for jcv, img and possibly ASR files. Eventually, these older SID files are going to become a storage problem for future map updates.

The 2597 shows 4 files.

D2656110A.SID 472 MB
D3398080A.SID 144 MB
D3157090A.SID 304 MB
D3406080A.SID 96.4 MB

Judging by the sizes, I don’t believe these extra sid files are from older maps. My first though was Garmin didn’t delete the files since the user may decide to backdate a map. But that doesn’t make sense since JCV files and ASR files are deleted and replaced with the map update.

Add member charlesd45 to the mix with yet again different files on his 2597, it’s getting more and more confusing and I have no answer. I’m wondering what, if any .sid files are on the 34XX, 35XX, and 37XX series.
At this rate perhaps Garmin will have to make units with 12GB memory to accommodate all these extra files.

Member charlesd45 - The 2597 shows 4 files.
D256110A.SID 472 MB
D3398080A.SID 144 MB
D3157090A.SID 304 MB
D3406080A.SID 96.4 MB

Just like JCV files, SID files are connected to a particular map version. The map update process deletes the ones from the previously installed map.

It looks like charlesd45's 2597 has older maps installed (2014.10, not 2014.30).

Also, there's a typo in the D256110A.SID filename. It should be D2656110A.SID

You're saying all the extra SID files are from previous map versions, so why weren't they deleted. I also wonder why the date stamps were then changed to match the latest download.
One would think the date stamps remained the same on older maps sid files.

That would indicate to me those that had 3 sid files
updated their maps two times (1 came with original map). charlesd45 who had 4 files updated his map 3 times.

I'm not convinced that is true, I'm sure they updated their maps more times.
Am I wrong with this logic?

I suppose by backing up and deleting the old files, then test the Nuvi for functionality would be a test to see if the extra files were needed.
I would do it to my own Nuvi, but at this juncture I wouldn't recommend others to try.

My 2460 only has 1 sid file, at each map update it deletes the old and adds the new, just as the JCV file does. Why Garmin would choose to leave the old sid files to take up space makes no sense to me.

Mine are different than Charlesd45. I have no idea what this means.

I have the latest maps. Update every quarter just like clock work. Unit shows 2014.30 and computer shows the same.
D2656110A.SID 472 MB is correct.

2014.3 was the second one. One right after I bought it. Then 2014.3.

So you've only done two updates since purchase, this rules out the theory these are older map files since you are showing 4 and only had 3 mapsets.

This should be a concern since if there are extra .sid files that serve no purpose, they are using valuable memory space.

Edit.Hey I made a big mistake on this.Got to thinking about what WAASup said about the maps.Re-checked and found that was my old backup file.Should be .

D2656130A.SID
D3157110A.SID
D3398100A.SID
D3406100A.SID

@muell9k, you misunderstood what I said...

The 2595 has three SID files for each map version.

Each file has a base filename with a sequence number that increments for a new map version (just like the JCV file).

For example, the Traffic Trends file for 2014.30 is D3406100A.SID. The file name for the 2013.20 map was D3406090A.SID.

WAASup Thanks for advising three SID files are requried for each mapset. However, that still leaves some questions unanswered. Why then do members NachoB, charlesd45, and jjen display 4 files when the old ones should have been deleted.
Mine and CraigW's 2460 only show 1 SID file, that unit has Traffic Trends and My Trend capabilities.

I wish I knew what each files function was that requires different identifying numbers. If it identifies different mapsets the numbers don't correspond. Why Garmin seems to complicate things never surprises me.

It that a typo? Shouldn't D3406090A be 2014.20?
2014.30 D3406100A.SID
2013.20 D3406090A.SID

I don't use trends. I don't feel it has a value. Why should it be such a large file?

Since the size of the SID files don't change over time* (at least as far as we've heard so far), I don't think the SID files contain a user's myTrend's data and therefore it may contain just the rules for how the nuvi device gathers data.

This is all guessing since we really don't know how Garmin uses the files, and except for the link provided earlier

http://www.pois-gps.com.ar/?page_id=2552/garmin/garmin-units...

we are assuming that the link's description of SID files is correct, complete and up-to-date.

A brave person would try disabling or deleting the various SID files, then see if/how their nuvi performs. The one SID file my 2460 has is not enough to warrant bravery on my part

* By "files don't change over time" I mean day-to-day additions or changes like would appear in the trip log. There apparently are changes to the SID files with each map update.

Thanks. I still don't understand why this new map update took up so much space.

There seems to be very little information regarding Garmin’s .SID files.
I had done some extensive Googling which brought me some undesirable sites to get some information.

I was able to identify the ID numbers and what their functions are for the 2014.30 North America maps.
I would of NOT delete those files since it may cause your Nuvi not to function properly on some features.

D2656130A.sid = external point addressing
D3157100A.sid = instasearch
D3406100A.sid = traffic trends
D3398100A.sid = fast routing

These files seem to be complimentary to the Garmin system and are probably used both directly and indirectly for route calculations and display.

Thanks for all your additional info. I guess I'll have to look elsewhere for space savings.

I emailed Garmin and they only said not to delete them.
Had requested more information then that. Sent reply back hoping for more information .

Makes total sense.

The reply back from Garmin on more information on SID files.

That file type is considered proprietary information.

That response from Garmin is par for the course.
The support person that relpied probably doesn't have a clue.
