I recently downloaded two files to my brand new Garmin GPS, Costco and Walmart locations. However now I know that I already have very accurate information for both so how do I delete these from my GPS?
Delete the .gpi file in the POI folder on your GPS.
Are you wanting to delete the files you downloaded or delete the files that come resident on the gps?
remove the files from the custom poi folder you use and then run the poi loader again. Any removed files will not be reloaded onto your unit.
You have a 1390LMT.
So others reading threads like this will have a firm base to work from, let me give some basics.
One should usually not "download" a POI file to a GPS. That would take up space and provide no future benefit that I can see and would take up internal memory. Reading other threads, it becomes apparent that many GPS units run into internal memory problems as new maps are larger due to both more data as well as new features like Junction View.
POI files should be "downloaded" to a folder on your PC. There are several good FAQs on this. Charlesd45 has one at http://www.poi-factory.com/node/25721
The POI files that one downloads are not in a form that a GPS will recognize directly (say, .csv or .gpx). They need to be converted to .gpi files.
POILoader is used to do this. Older versions of POILoader ALWAYS created a file called poi.gpi (which "replaced" any file on the GPS by that name). The latest version of POILoader lets one choose a name for the output file. For example - using the files mentioned - dfpinos could have run POILoader and created a costco.gpi file; then, he could have run POILoader again and created a walmart.gpi file; or, alternatively, he could have created a costowalmart.gpi file had both POI files been in the same "folder" on the PC.
It is easy to get rid of these .gpi files on the GPS. One can use the latest POILoader to do so. Or, one can go directly to the [gps]:\Garmin\POI folder and delete them.
HOWEVER - before doing any deleting from the GPS, PLEASE PLEASE follow the instructions in http://www.poi-factory.com/node/30394 to backup up the GPS.
@dfpinos, I assume you are saying that the internal Points of Interest have all of the Costco and Walmart locations in your area and that your lifetime map feature will keep them up to date. This may be true in your case in your area.
However, in may case, my last map update sent me even further into the unknown than when I first got my unit. It used to be that I had at least 50 Subaru dealerships on my built in POIs - BUT NOT THE ONE IN MY HOMETOWN FROM WHICH I PURCHASED THE VEHICLE. After this latest update, I only can find 4 instances of "subaru" when I do a Where To > Points of Interest > Spell Name.
My point is that poi-factory files may turn out to be more accurate over time. This is especially true when you are traveling. As you know, Walmart is forever building new stores. I give you an example at http://blogs.laweekly.com/informer/2011/09/wal-mart_socal_bu... where the headline is "Wal-Mart Plans to Sneak 15 New Stores Into SoCal, Including Burbank, via Permit Loophole"
Informative and factual post. As they say in Australia; "Good on ya mate".
Thank you not only for the information but the teaching.
