Hi, I got a message on screen advising me to update my software. I connected my Garmin to the pc and downloaded the upgrade. When it was finished I disconnected and switched off the unit. Now the Garmin won't swtich on again. I've tried
- charging it in the house
- plugging it into the car
- connecting to the PC again
Nothing happens. Any suggestions?

You can purchase map updates from stores that sell the units, or new this year you can buy updates for the life of your unit from the Garmin website which cost $120. You can get up to 4 updates per year. If you wish you can just purchase a single update for $70.
Reset button behind the Antenna, press this in for a few seconds.
Use the Web-updater at Garmin, to update it too,
Jack it to a PC and run the update,
If still playing up, Use the Firmware update at Garmin for it,
(( google Garmin 660 software updates ))
Should be good then
However, Garmin released 3.4 which will include the changes in 3.1 and also makes the bluetooth compatible with more phones.
You need to go to www.garmin.com and download their webupdater and run it with your Nuvi connected to the PC with a USB cable. It will check (via the Internet) if you need a firmware upgrade. The latest firmware version for a Nuvi 660 is v4.7. There is a second menu after the main firmware option that allows you to select additional software. Select yes and check the bluetooth 3.4 box and the Chipset "G" box if it's shown.. The Chipset "G" is the upgrade for the receiver in the flip-up antenna. Let it download. When finished, select to safely remove the Nuvi. You can now unplug the USB cable. Your Nuvi will reboot and load in the new changes. Whatever you do, don't turn your nuvi off! Let it go and update. You will see it say "Loader", then "Loading Software" and you'll see a task bar that says "Updating Bluetooth Software" and "Updating GPS Software" (if required). Once you get to the main menu and there are no more texts coming up on the screen. Press the power button and turn your unit off and then back on again. Check the GPS and Bluetooth firmware versions in your Nuvi. It should be 3.0 for the GPS and 3.4 for the Bluetooth. Check the firmware version if you selected v4.7. You will have to re-pair your phone with your Nuvi as the update erases any previous set-up. Let me know how it went for you. If you have trouble with this, let me know. I can do it for you. I have done it many times. Please rate my solution if you found it helpful.
It depends on how the files were corrupted. If the source of the corruption is not physical or magnetic damage to the memory chip where the software is stored, you should be able to reinstall the operating system software and the new maps right from your own PC.
First I would recommend going to the Nuvi 660 page in the Garmin website, look for the link to "downloads and updates", and download the most recent software update. The update is free.
Once you have done that, try reinstalling your maps. You can only load Garmin maps into your Nuvi.
If you are in the US and your memory storage is not damaged, I can update your GPS and install the map for you if you prefer.
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.
Have you updated the software since you purchased the unit? If not, go to Garmin's site, download WebUpdater and check to see if there is an update to the unit's software. If so, download this and see if it helps. If not, try downloading the same version of the software again. This might help also.
1) Turn on unit 2) Press VIEW MAP 3) Press SPEED in lower left hand side of map 4) This will bring you to the Trip meter screen on this screen press the round speedometer at the top of the screen for about 10 seconds this will bring you to the SYSTEM BIOS. 5) From this point forward be careful you can mess up your unit by changing the wrong thing. 6) Press NEXT until you come to the BLUETOOTH STATUS screen. 7) Now press UPDT P this should complete your update.
