1 - When I try to use the POI Loader to install the POI .gpi files onto the SD card in my Nuvi 660 I get this error message. If I put the same card into the SD card reader connected to my desktop, the POI Loader will correctly write the .gpi files to the card. I believe the problem is my Nuvi believes the card is write-protected, since I get an error with that message if I try to copy anything to the card using USB if it is in the Nuvi. The SD card is 4GB formatted for FAT32. Any ideas what is wrong ?
2 - So, I put all my custom files onto the card as above, put it back into the Nuvi and booted it. All the POI files seem to be okay , but whenever I boot I get a screen that says there is new data on my device, and I can figure out how to stop that screen from showing up. Hitting Cancel skips it, but it is kind of annoying. Anyone have a fix ?
As far as not being able to write to the SD Card when it's in the desktop, on the adapter you are likely using, there is a physical switch on the side that is a write enable switch. It is likely in the READ-only position. Sliding it to the other position should take care of that issue.
It works in the desktop computer port but not the reader of the nuvi.
Not sure what the issue is but maybe try reformatting. As for the wanting to install the "new" files to the nuvi, that is normal on that unit. you have to either install to the nuvi or, as you did, ignore every time.
On all the units I've had where I've used POIs on a card you only get asked the question once ...
If you ignore the message to install to the gps or don't answer no for installation to the unit. You will get asked each time after booting up your device. I had a 265 you actually had to say yes to get to the no screen.I believe that was what the poster was saying.
It was a convaluted way to so "no- leave it on the card".
That topic of the nag screen came up a lot in the past. Not really sure how the newer models handle it.Haven't done it in a while but I believe on my 2597 once you answer no that's it.
I agree with Charles, I still have my 660 has a backup and I also answered NO to the message. I didn't get the nag screen the next time I rebooted.
I had on particular adapter, where the little switch probably stuck out too far. Every time I installed in the PC, I got the error message.
I have tossed that adapter and the problem went away.
