Blank Screen on Garmin C330

Hello, Go to the internet and get the phone number for the manufacturer of your product. Call the product tech support and they will either replace or tell how to fix the unit.

Garmin has released new maps. Most of their units are entitled to a free update if the unit was purchased recently Just a heads up to anyone who recently purchased a C330. According to Garmin's tech support, the map udate 2008 is not free to those of us that recently purchased a C330. Only to those who purchased a C340 and up. Their excuse is that it is a "low end" unit, and also that the memory cannot hold the full US maps on the DVD. Gee, I can purchase the update for $69.99 and load a subset of the maps if I want, according to the person in tech support, but I cannot receive it as a free update. So, apparently buyer beware if you purchase Garmin's "low end" units. You will apparently not be able to receive a free update of maps, even if the unit you buy is already out of date.

Did you contact Garmin tech support? They are pretty good at it.

IS the battery charged fully? Try turning it on while its plugged in.

Problem resolved. It seems to have taken several hours for gps to update.
Thanks anyway.

Fixed. Called Garmin. It seems that version 4.90 FW on the Nuvi 350 (which came shipped on my 350) has a bug where it cannot communicate with the Garmin software either to update maps or update FW. Tech from Garmin e-mailed me a patch that I copied into the Garmin folder on the Nuvi itself, via USB and Windows Explorer. I then rebooted it; the patch installed itself which then allowed the unit to communicate with the map upgrade software and all is well. 2009 map update is now installed and the Nuvi is working fine again. Haven't tried upgrading to newer FW yet; will probably leave well enough alone.

2009 upgrade data is too large for garmin 330 must have sd card

Turn on the Garmin. Look for the little wrench on the screen and select it. Now look for Map, select Map. Now look for Map Detail. Verify that it is set to "Normal" or Higher to get more map details.

put your thumbnail under the silver faceplate above where it says garmin and on the right you will see a reset button. It will reset your garmin and you will not lose your information. Hope this helps.

Have you tried a Master Reset? If not, it may help, but it WILL ERASE ALL OF YOUR FAVORITES, and may remove anything you have updated. To do a Master Reset, turn the unit off. Press the On button and the bottom right of the screen at the same time. Release the On button, but keep pressing the screen until the unit asks if you are sure you want to reset. Press yes. This may help.
