I have the same unit, and recently added about a dozen different sets of POI's, doesnt seem to have slowed the unit down at all.

The technical answer is "yes" it will slow down the redraw, but will it be enough for you to notice? Not likely, unless you have several icon files clumped close together, like several restaurants in a row, but even then, I doubt you'll notice it.

The amount of memory in the GPS is far more than it needs to do it's job. The contents of the files are primarily text (ASCII) information. The amount of memory a text file takes up is very small in comparison - so you should be able to put thousands of POI points into the system w/o a slow down.

I also have included a number of POI's for Garmin. Makes no difference in speed of the device.

Cheers

I have a garmin navi765 and have loaded some 33,000 custom POIs and a 4gig SD card loaded with MP3 files and have not noticed any slowing of the unit performance.

I guess the more data must slow it technically, but I doubt you will notice it.

Regards.

Hi
How did you load the POIs? I used the POILoader and can see only the last lot of POIs on the 765T. Do I have to have all POIs, new and old, in one big file on my PC which to point the POILoader to?

Thanks for your assistance.

One thing you might consider doing is removing from your unit (deleting) all the voices and help files in languages you don't use. I did so and it freed up a substantial amount of room (memory). You can always reload them later if you want to. I have almost 30,000 extra POI's loaded and don't notice much difference in speed.

Hope this helps.

pjnuk,

The poi loader combines all of the poi files in the source directory into a .gpi file. This .gpi file is either loaded directly into your GPS, or you can put it onto an SD card and load the file manually from the SD card, but the GPS will delete all the previous custom poi locations when it imports the new file, so if you wish to keep all your old poi's, you have to make sure that the csv or gpx files for all your old locations are in the one folder along with all the new locations.
