My Nuvi 660 Has POI File Limit of 20

 

I decided to do some maintenance on my POI files on both my Nuvi 660 and 2460 and came across an issue on the 660 that has baffled me after spending countless hours in seeking the answer without finding one.

I have a total of 29 POI’s, 12 of them are individual POI’s, and one POI contains 17 (mostly stores) are in one POI file.

To simplify updating POI’s, with the file containing the 17 locations I decided to make them individual files for a total of 17 separate POI files in addition to the 12 separate POI files I already had.
.
Using POI loader I created 29 individual files and saved them on my PC as I always do. I then copied the 29 files to my 2460.
No problem, everything went smoothly. I did the same and copied the 29 files to the 660 only to discover that only 20 appeared.
Memory is not an issue since the 660 has 126mb of free memory, nor do any of the POI’s have Tour Guides. The total size of all the POI files is 12mb.

I then copied the missing 9 POI’s to an SD card, I got the message, do I want to add to internal memory, and I answered with yes.
The files were not copied nor did they appear. I did the procedure again and this time I replied no in hopes of it would read them off the SD card, no luck, they didn’t appear, still only displayed 20 POI's. No files are corrupt since the 2460 recognizes all.

Lastly what I did was copied the 12 individual POI’s and then created and copied one file containing the 17 POI’s to the 660 and all files were recognized. My only logical conclusion is that the 660 has a limit of recognizing only 20 Individual POI files. I’m certain if I created 20 POI’s with hundreds of locations it would recognize them since it remained under the 20 file limit.

Is this 20 file limit common knowledge I’m not aware of?
Any comments would be appreciated.

I'm not aware of those units having a POI file limit but back then when these units were released and in use, I believe we pretty much loaded just one file at a time.

Maybe you've discovered that 20 file limit.

I did try 1 at a time

I did try loading one at a time also, what's confusing is that all 29 separate files show up in Windows Explorer as present in the POI folder, yet when I bring up the Custom POI's, 9 locations are missing and only displays 20 of the files.

It's no big deal, I can still have all my POI's but will need to include several locations into 1 POI. It just makes it a bit more difficult when wanting to update only 1 POI.

Since there are probably very few members still using a 660 I doubt I'll ever know if it's only my Nuvi or the 660 actually has a limit on POI entries.

a guess

This is just a guess but I do remember something way back about this problem or something similar to this device. I believe the user ended up taking out some files from the sub folder and adding another subfolderto put them in. The files had to be split up.

its time

looks like it time to buy a new one!
Just Sayin!

What else is in that folder

On your 660 what other files are in the folder having your POI? If there are other files other than the GPI ones, you may have reached the 32 file limit for a folder.

Honestly, I don't think loading individual files saves any time or effort. If you update multiple files, you have to rum POI Loader multiple times. Loading a single file with subfolders means POI Loader only has to run once. Your 660 is USB1 so molasses moves faster in Barrow, Alaska in January than running multiple iterations of POI Loder.

Thanks for the reply. I just use the 660 as a backup to my 2460 so it's just an inconvenience if I have to add additional sub folders. I kind of enjoyed the challenge but disappointed in the results.

Believe it or not the 660 has the original 8 year old battery and still holds a charge as new. Just don't make them like they used to.

Right about that. Still have my 265.Doesn't have all the bells and whistles but still solid as a rock. Can still depend on it.

No other GPI files in the POI folder or anywhere on the GPS or SD card, and only 1 .GPX (current.gpx).

I don't routinely update the POI files except for the Redlight, and Speed Cameras. You have a valid point about only having to run POI loader once. How right you are about the USB1 on the 660, painfully slow. I wish Garmin would use USB3 on their future units.

RV 660 LMT?

Just got an RV 660 and inserted the micro SD card from my Nuvi 2699 with thousands of POI's and could read each one; no problem. The RV 660 also came with maybe 1,000,000 POI's pre-installed.

Most Garmins don't limit the number of custom POI by file count but there are other limitations that do come into play. You are limited to 32 different location files within any one sub-category of custom POI and there is a limit of 32 categories. I haven't heard of anyone running into a limit if they don't use categories but then again, there is a finite amount of storage available on the unit. Using an SD card does remove the memory capacity limit as you can use up to a 32 GB card in all but the very earliest units (which are better displayed as museum pieces).

I'm a bit confused by this post in this thread, since I just now ordered a new RV660LMT (which is a new Garmin model!) and am now curious if you are asking if it has the same issue as the older nuvi660 the o.p. was referring to, or are telling us it doesn't!

Yikes.. I literally just ordered one, so I'm biting my lip as I type!

edit .. I read the post & panic mode set in so I started typing.. I now see that you are indeed telling us that the RV660 reads gobs of files just fine!! Whew, Thanks!, and .. nevermind my posts, lol.

It's about the Line- If a line can be drawn between the powers granted and the rights retained, it would seem to be the same thing, whether the latter be secured by declaring that they shall not be abridged, or that the former shall not be extended.

Yup...

Relax. A RV 660 is several generations newer than a nuvi 660. smile
