Garmin nu360 shows no map data available and in map detail- map infor. button is inactivated.

Is the SD card containing the map (and update) inside the Garmin device yet ?

Locate the reset button, located on the back of the device, in the lower left corner. Remove the sticker covering the button, and use a straightened paper clip to depress the tab.

To reinstall maps

Connect your Garmin Nuvi to your computer via USB cable. You can only update the maps through connecting to your computer.

Open the "myGarmin" website and sign in with your Garmin account. Make sure to sign in with the account that you've purchased the map updates on.

heres a link to the site;


http://my.garmin.com/mygarmin/login.htm.

Click the "myMaps" tab on the myGamrin dashboard. This will load a list of all of your purchased map upgrades.

Click the drop-down menu in the "Recent Map Purchases" section. Select your Garmin Nuvi from the list of devices.

Install the Garmin Communicator Plugin when prompted. This is required in order for the Garmin website to transfer the map files to your Gamrin software on your computer.

Download and install Garmin Express. This is the program that allows your computer to interact with your Garmin Nuvi.

Register your device in Garmin Express. If you haven't already registered your device, you'll be prompted to when you start Garmin Express. You'll need to register in order to update the maps.

Click the "Updates" tab in Garmin Express. This will show all of the available updates for your Nuvi, including the new map update you just purchased.

Click the "Show Details" option next to your Map Update. Click the "Install" button that appears. You will need to accept the agreement before the update installs.

Wait for the maps to download and install. Once you agree to the terms, the map update will begin downloading to Garmin Express, and will then be transferred to your Nuvi. This will likely take several minutes to complete.

Close Garmin Express and unplug the Nuvi when the update is complete. The Nuvi will reboot and begin installing the updated software on the device. This may take another couple of minutes.

If you weren't automatically prompted to install Garmin Express, you can download it from



http://software.garmin.com/en-US/express.html.

Make sure that your map is enabled with a check mark on the map info screen. If the map info button is grayed out, then this means that your map is missing.

hi bud, just had the same problem. hard reset i.e turn off unit, hold down ok, page and then the power button at the same time. it should then ask you if you want to delete all data. select yes and then you should be able to upload your maps again, this worked for me good luck

Have you checked the wrench menu, map info, the preinstalled map should have a check mark, if not tap on the check box, it should now show a detailed map screen when you go back to the main menu and select show map.

Did you try to perform a map upgrade to 2008? Turn on the Garmin and from the main menu touch the wrench,
then press Map, then look for Map info.


This will show the the current map version installed

Did this problem occured after trying to install an update?

Try doing a hard reset on the Garmin

First remove the faceplate from the Garmin C330. To accomplish this there is a small indentation under the word Garmin where you can get a finger nail in and pop the faceplate off. On the right side of the unit is a reset button.
