Garmin C530 i just got my garmin c530 and i loving it except that the screen goes black and it wont power on it has down this to me already once before and i followed the soft reset instructions on garmins website and it worked again but this is the second time it has down this to me and it will not allow me to do the soft reset again theres no power to it seems like ... what should i do?? is there a way to hard reset it?

try resetting the unit by popping off the frame around the screen where the reset button is.

I just purchased my c530 a couple of days ago and had been loving it. I had added some custom POI's to my sd card using POI loader version 2.4.0 and that had worked fine. Then the other day I tried to load some new custom POI's, but POI loader got hung up and froze. After disconnecting the c530, I restarted it. After it started, a screen came up that said "No detailed maps found that support routing. The Streetpilot cannot be used without them." I contacted garmin, here is the site for contact info since I am unsure where you are. http://www.garmin.com/garmin/cms/site/us/support/supportcontactand the tech support at Garmin. They said that somehow the files on my c530 must have gotten corrupted. The person I talked to at Garmin was very friendly and walked me through several things trying to get my unit to work. He was very apologetic and said that this should not have happened. He told me I would have to return it and get a replacement. Sorry Hope this helped.

I don't think there is one.  I had to buy an $80.00 CD-ROM for mine.  

I did find an article about this here: http://www.gpsmagazine.com/2007/08/garmin_map_update_not_so_smoot.php

The problem is with the battery, DC will not fully charge the battery to its required capicty to work. You need an AC charger and to charge it fully ( 10 hrs Max) and then try it. It needs a lot of power to drive the screen and connect to satellites.
Invest in an AC charger and all should work properly

Hi

You'll need to enter the serial number of your device, only after that you'll be able to select your c530 device from the list. However, if its not showing there then you can visit this link for update installation of your C530---

Hi,
Pop the face off to reset it, could sort it for you.
Press the power button for over 1 minute to calibrate the screen
and use the Garmin Web-updater to update the software.

Should be good then

Did you reset it? lift off the cover plate by slipping your fingernail into the little slot just beneath the Garmin logo. There is a reset button hidden under the cover...

Carefully remove face plate bezel. There is a reset button on the right side of the face. Press the button and then restart normally. It's in the owners manual if haven't lost yours like I did. The manual is on Garmins website.

My Garmin c350 has a green screen after trying to update it for the first time and my computer will not read that it is connected.
It will not shut off after holding the power button down for 3 minutes

According to technical support, the "glitch" has been fixed with the latest web updater on the Garmin site. In the meantime, you will need to leave the unit unplugged for upto 48 hours to allow the battery die and the unit to get out of its "hang up". Once the battery is completely dead, plug the GPS into a computer (USB) and it should come back to life. Then do the update.

Hope this helps.
