Re: Blank Screen on Garmin C330
It took a nap...
Waking up your c330...
If you left your Garmin c330 on running the battery will have 1% life left. If you turn c330 back on again, it will flash screen for 3 seconds then die, even charging it at this point will not wake it back up. TO BRING IT BACK TO LIFE... plug in the power home or car into Garmin c330. There is a tab in the front Garmin gray frame of your screen. You must take like your fingernails and under the logo "GARMIN" pull the whole gray plastic frame off. Underneath the plastic frame to the right hand side. There is a "RESET" button. Make sure power is plugged in while hitting reset. Your battery should come back to life. Cheers

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 You will apparently not be able to receive a free update of maps, even if the unit you buy is already out of date.
You need to have Garmin Tech support send you this attachment; "gmapprom.unl" Then follow the instructions below.
Save the attachment from our message to the desktop
Right-click the file gmapprom.unl, and click copy
Click on My computer
Click on the Garmin Nuvi drive
Click on the Garmin Folder
Rightclick a blank white space in this Garmin folder
Click Paste, and note gmapprom.unl file is listed, please also delete
gmapsupp.img if present
Unplug the device, and allow to start up
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.
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.
