Maximum Number of POI's - The Practical Limit

 

I was helping a fellow poster understand why he could not load his POI's on his numi 660. POI Loader hangs.

He has 195,812 POI's in 12 dirs and 137,823 in a 13th dir, lets call it Water. All are good with no problems.

The 333635 POI's loaded into my 750. Most files were OK but a few of the large ones near the end would display only 4 POI's. The scroll arrows were disabled. When I loaded the first 12 dirs only all was OK. When I loaded the Water dir only all was OK.

I should point out that the 750 was rather slow on some of the larger POI files and the 12 dirs.

So I concluded tha if you can tolerate the slow response then about 200,000 POI's is the limit. But the number of dirs might also be a factor.

Any thoughts?

Marine use?

Are you creating channel paths to follow in marine environments or something? These numbers are staggering.

Water

The water POI's are from of lakes, piers, lighthouses, dams, etc. Not marine in the sense that you asked.

Not Necessarily

On my 760 4gb card I have 30 folders with a total of 1,131,546 POI's and I have no sluggishness at all and it loads fine. I have not copied anything but the updates to the nuvi itself. Don't know if that is the reason I don't have a problem.

.

I've had a million+ loaded to both my Nüvi 310 and StreetPilot C510 (as an experiment, more than anything). It made both of them noticeably more sluggish than normal - though everything was functional.

My guess is. that it probably depends on the 'density' of the POIs, as much as anything...

No SD Card

Since I don't have a SD card yet I loaded all of the POI's in the main 750 memory so perhaps that is a factor.

I didn't check the file source but many are from this site. The sluggish files I saw had about 2500 POI's in the file, another factor.

The size is 18.2MB for all of the 333,635 POI's which doesn't strike me as excessive.

I had about 100k loaded,

I had about 100k loaded, with promixity alerts for many POIs, which slowed my nuvi 680 to a crawl. Took out proximity alerts and it worked ok.

I think some of the practical maximum has to do with alert thresholds.

Million Plus ?

What do you guys do with a million plus POI's,are you really going to that many places? Nothing wrong with it, but it seems like that would be a lifetime task.

WoW!

I now have 49,650 pois loaded in 9 directories.
I have been chided as being a "newbie" because I don't have "many" pois loaded... but I don't know that I need everything in the world loaded on my Nuvi.... and if I did.. I could certainly see a "sluggish" operation just from the amount of data.

Since many of the poi files are downloadable from places, why not just load up what you will "normally" use... and then re-load as you go to specific loacations?

This way, you will get the "latest" rendition of the poi file and have all the latest updates to it.

Just a thought...

.

That's what I do.

That's how I do it

That's how I do it too.
Each trip - which are typically 2500-5000 miles thru 10-20 states I filter the POIs that I want for those states that I will be traveling thru with POI Verifier.
Just my choice so I make sure I am not loading up my Jack or Jill with unneeded POIs.
I do have ALL my Custom Pois loaded onto a memory stick that I take with me just in case. Of course, I had my laptop with me also !

My personal choice !
