Downloading More Waypoints

[+shunra]

When new waypoints are loaded, what happens to the old ones?

 

My Map76S has room for 500 waypoints.

 

I uploaded 400 caches from pocket query A.

 

A few caching days later, during which a few new caches appeared, the same PQ (A) produced 400 caches again. Upon uploading them, I noticed that the new ones were added, whereas old ones (including those which I had found in the meantime and were not part of the 2nd download) were still there (and I had to delete them manually). This means that a new download does not delete existing waypoints as such, which is good.

 

I then uploaded 200 caches from another query (B ), which has some overlap with PQ-A, but certainly not as much as 100.

 

What I cannot see now is: did the upload of the 200 lead to deletion of some of the original 400 caches, and if so, which ones of the 400? Or does uploading just stop when the 500 limit is reached (and if so, which of the 200 don't get uploaded?)

Once you hit the limit, no more NEW waypoints are going to be added, of course. The only question is whether, when you attempt to upload a waypoint that has the same name as an existing waypoint, does it overwrite it, or is the original left intact? Don't know, but you could find out with about 2 minutes worth of experimenting.

That's not 'of course'. It is equally possible that some existing waypoints get pushed out, according to the FIFO principle.

 

FWIW, After having loaded 400 and then 200 into a unit with a capacity of 500, and having good reason to be sure that all 500 slots are occupied, I uploaded one single waypoint from a gpx file with just that one waypoint in it. And guess what? It was uploaded. This means that one of the pre-existing 500 must have been pushed out. But which one - that's the question.

They do. I tested that first, by uploading the same waypoints, once from a GPX file (they got uploaded as geocaches), and once from a LOC file (they were all turned into unspecified waypoints).

First thing you need to do with that Garmin 76S is update the firmware.

Its free and it will double your waypoints from 500 to yes 1000.

I keep 900 plus caches in mine all the time..

Is there a firmware upgrade which can increase the number of waypoints that a 12XL can hold? I am limited to 500 right now.

Hello

I looked on Garmin's site regarding the model you mentioned. I could not see where they had increased the waypoint storage. You might contact Garmin to see if it is possible.

I guess this is "software" not "firmware". Since this is a upgrade you can

do without sending it to manufacture.

 

Anyway most of the upgrades are of no use to me.. but that one doubling the

waypoints is very nice.

First off, if your software release is greater that 2.01, then your unit hold 1,000 waypoints, not 500. Second, did you confirm that the last waypoint uploaded didn't have a waypoint ID the same as one already loaded?

 

I would be extremely surprised if the Garmin software silently erased a waypoint, under any circumstances.

New waypoints are added up to the unit's capacity. After that, you cannot upload any more new waypoints until you have deleted some old ones. The GPSr will not delete 'old' waypoints based on FIFO.

 

My pocket query gives me about 400 waypoints. I clear all waypoints from the unit before loading the new ones. I don't need to keep waypoints of caches I've found. If I have an important waypoint I want to save, I can choose to save it to EasyGPS before erasing it from the GPSr.

Ah, that explains it. I'm using version 3.60. Thanks!

Yes, me too - I was!

That's comforting!

I delete caches as I find them, and just overwrite the existing waypoints with a new upload of the same query every now and then. Deleting existing waypoints is not necessary, except if you want to upload a different query and have no space left (a problem I apparently no longer have ). Besides that, i can just delete the geocache-type waypoints, rather than *all* the waypoints, and if there is a specific one I want to keep, I just turn it into something else, along with some other permanent waypoints (like 'home', etc.)

I usually delete caches as I find them also, but I still end up close to my 500 waypoint limit (400 or so from the PQ, then the other 100 for parking coords, etc).

You can also use EasyGPS to filter out waypoints outside of your caching area. My PQ is for my whole state, but I can edit it with EasyGPS to leave out caches in say, Las Cruces and Portales unless I plan on going there within the next week.

You may change your mind after you've spent an hour searching for a cache that was archived 2 week ago.

Good point.
