Problem with a Nuvi 3790T

I recently purchased a new 3790T. I have a 760 as well. I copied directly some POI files from the 760 to the 3790T. The files I copied are the NSW, VIC and QLD school zones GPI files and a speed cameras GPI file. Boot up my 3790T after that and all works fine. No problem.

However, my problem is I don't seem to be able to get rid of those files that I transferred to my 3790T from my 760. I tried removing them using the POILoader file but to no avail. I even deleted them physically from the 3790T POI folder. But every time I boot up the GPS, the files returned. Anyway, I decided to just proceed and install the poi.gpi file that I created earlier to my GPS using the POILoader. I checked and the sure enough, the poi.gpi file is in the POI folder. I unplugged the GPS and boot it up. Simulate a few routes then thought I plug the GPS again to check the POI folder. Surprisingly, that poi.gpi file has disappear while the rest that I transferred from my old 760 are still there. So what happened to that poi.gpi file. It is all very confusing and I am not sure if I am now having the latest update or not.

Does anybody who owns the 3790T know what is happeneing? Sorry as I am newbie with this sort of update so I hope I am making sense. Thanks.

Don't think it is wise to transfer files from one GPS to another. You should have the safety .gpx files in a directory on your computer then use POI loader to create one file called POI.GPI and send it to the GPS. Suggest deleting the POI.GPI file in gps and loading all the school zones via POI loader.

Faulty unit

joh, thanks for your reply. As it turns out, my unit would not boot up last night. I returned it to the shop and now got a new one. I did suspect there is something wrong with the unit as it did crash a couple of times. Hopefully this unit does not give me the problem like before. Cheers.

EDIT: OK, with the new unit, although I am able to upload the poi.gpi file, when I boot up the gps, it does not register any extras or any custom pois. So I connect the gps to my computer again and use webupdater to check for latest program. The program confirms that it already has the latest software but I chose to reinstall anyway. After that, wallah, it now recognises the poi.gpi. So anyone with new 3790T not recognising the uploaded poi file might want to try this out.

Sorry forgot to add another quirk about the brand new 3790T program. I transferred my favourites from my old 760. Again, before I reinstall the program, it does not register the favourites. But after reinstalling the program, it then registers the favourites. So probably best to just reinstall the program before you proceed to upload poi or transfer favourites.

Re: Problem with a Nuvi 3790T

To delete custom POI, you should update your POILoader to latest version. Run POILoader, then find out the unit, next to choose the clean (dele) function to clean up the custom poi record of 3790T.

Garmin 3790T software bug

This is a common problem - I have spent hours on the phone with Garmin support. I have returned one 3790T and now have a replacement. Was told its a software bug.

Have you downloaded the most up to date software?

Garmin 3790T software bug

Mpearson, I definitely have the latest software. Each time I upload the latest POI file, I need to run the Webupdater and re-install the latest software for the gps to register that new POI file. So yes, definitely have the most up to date software.
