POI Loader Limit

I have seen posts in the past of not more then 32 subfolders showing up on the GPS.It sounds like that also applies to the number of files in a subfolder .Looked on the help menu for PoiLoader and didn't see anything.It may be buried into a short sentence somewhere.

Yes the 32 file limit per folder has been around on the previous version of POI Loader. Also the max number of Custom POI folders on Nuvi 350 is 256.. not sure about other Nuvi models. That's 32*256 = 8196 Custom POI files allowed.

Also recently with my Nuvi 350 I have 1,014,699 Custom POIs, using 21 folders and 403 files.

Ok, am I missing something here? If it won't hold more than 8196, how do you get over a MILLION ITEMS?
I gather that the POI FILE containing maybe 2000 POIs still counts as ONE? Just when I thought I was getting a grip, I slide down the slippery slope again.

How is that confusing? You are missing something. There are many POIs in a file! Some files like the McDonalds (a single file) has over thirteen thousand POIs.

I have 21 folders with 403 files and 1,014,699 Custom POIs entries. There is no known max for Custom POI entries, just files and directories.

Yes, I made an error in defining file as a single POI instead of the whole listing of that particular data base.

Being able to load over a million POI I find fantastic.

If you combine on your GPS a couple of folders, say the way they did the combined rest stops of all the states, they were in effect making ONE file out of many.........and I could do that with POI for my address book and waypoints on various roadtrips.

Correct me if I am still wrong, I'd appreciate it.

Sure you can combine any number of POI files into one file. It will just not be as easy o find an entry since you will not a separate listing when viewing/search from the GPSr.

I just checked my 660 and it's 3/4 filled. will that slow me down any. Should I put it on a SD Card ?

How did you check to see how much free space you had? Was that something you did from your Garmin or from the PC when the Garmin was attached?

From the PC when the Garmin is attached. Open My Computer and then double-click on whatever drive letter was assigned by the PC. You can look at all the folders & files just like you can with your PC's C:\ drive.

I never thought of that!

I once got a POI-Loader error message when I had more than 32 POI files within a subfolder, but did not know that there was also a 32 subfolder limit. Thanks for asking about this. I guess I've reached my subfolder limit, as I have exactly 32 subfolders now.

No please read my post at the beginning of this thread. There is a 255 limit max for folders. Other post have reported with 256 your GPSr (Nuvi 350) will turn into a brick and need to be sent to Garmin. Also there is special install image to recover such a case.

AIUI, there was a problem that manifested itself as a 257 folder limit - but that was just a vagary of the test data - and it actually turned out to be related to the number of custom bitmaps.

The special image, was just an early version of the firmware (in .RGN format), that didn't support Custom POIs. (So it didn't hang at boot time, giving a chance to clear away the offending POI.GPI)

But this was all fixed a good while ago...

Hornbyp,

Thanks for the correction and clear explanation. I was recalling what I previously found and well was lazy to look up the details.

OK, I'm now confused.....How many folders can you have on the Garmin memory today and how many on SD Memory today and still read the files on the GPS?

Then, How many files (.cvs) can exist within one folder and still read the files on the GPS?

Is it Garmin model dependant?

What causes or establishes the limits?
