My navi 600 said s d card not inserted - GPS

you have to put it in straight. when it gets 3/4 of the way in you will feel a little bit of resistance. push steady until you hear it lock in. hope this helps

I have the exact same problem. All my flash cards worked fine, and all of the sudden, none work. Not even the one that came with it. I am still trying to fine the reason. I bought it eight years ago, that might be it.

Check for a scratched or dirty Navi DVD disc. Clean or have the scratches polish out at your local game store. Video game stores usually have a disc repair machine that polishes out scratches.
Note: In some cases the Navi unit can cause rotational scratches on the DVD. If this is the case than the Navi unit will have to be replaced.

On the CD that comes with the device there is a folder for the Navi software which contains sub folders. Simply copy the whole folder from the root directory to another SD card and insert into the device and reboot. This probably also works if you overwrite the Sd card that comes with the GPS.

Download you model manual for location:

put them on the sd card from your computer, and then insert the card into the treo.

delete some files or folders from ur mobile and try to transfer the data
