Open Question

My Garmin 775t nuvi keeps on looping at boot screen

What i did for the 775t to work again I took the battery out, wait a while but the 775t nuvi is doing the same thing. It keeps trying to boot load the maps and then it goes blank (it turns its self off). Everything started when i tried to load one more map on the Garmin directory, included the keys ofcource in the unl file. I really need to hard reset the garmin 775t to its factory default erasing even every extra maps added in it. Thanks Dimitris

reset by turning on and keeping finger on the screen then clicking 'yes' to 'reset all user data".
try hooking it with computer connecting usb wire several times as sometimes if it is not getting connected this happens.also try to check out in any other socket of usb in your computer.

Is the battery charged? What does the battery indicator say? If you are using it in the car, is the power cord connected and working properly? If it is working correctly, you should see a lightning bolt symbol over the battery bar graph showing that it is connected to an external power source and that it is charging.
Try plugging it into your PC and looking at the battery indicator. Do you see the lightning bolt? Does it shut off when your using it on the PC? If not, there is something not right with the car adapter. Also, just because it was plugged into the car adapter does not mean it was charging. Many cars will turn off the cigarette/accessory jack when the ignition is off or shut off after a short while to protect the car's battery from being run down. Try hooking it up the the PC overnight and leave the PC on. In the morning try using it. Does it still shut off? If so, the internal battey may be bad. If it works and doesn't shut down, you have a problem with it not charging in the car and the adapter may be bad.

SOURCE: Have a Garmin nuvi 200 with North America maps.

It will depend on how much memory you have in your Garmin. If you have maps that you want to keep then I would download those first and then add in the Ireland maps. Or wait until you leave to add in Ireland. I believe the Garmin will tell you if there isn't enough room to add in Ireland.

Gamin nuvi 1450 wonot start and the gamin express cannot recognize it


Your Nuvi has to boot past the Garmin logo to the main screen before it can be recognized by your PC. Is the unit dead? The Nuvi 14xx series is well known for its problem with the rear USB port coming loose. This will prevent the unit from receiving power from the external charger and will prevent the battery from being charged. If the unit goes into a boot-up loop, displaying the Garmin logo then shuts down, this is often caused by corrupted files, such as a map or bad firmware update. See these two links for more info:

Nuvi Blackout


This is a known problem that Garmin is fixing. Look at:

http://www.garmin.com/garmin/cms/site/us/support

Under "TOP FAQ" there is an entry for "My nuvi 755T, 765T, 775T or 785T will no longer turn on."

You will need to return your unit to Garmin for them to fix it.

Garmin Nuvi 660 touch screen freezes up. Soft


I sat on the phone for 30 minutes waiting for Garmin support when my Nuvi suddenly had no touch screen response. They had me delete a file on the device (with it hooked to my computer) then reboot and it went thru a touch screen alignment and it worked.

Sadly, it has frozen again and I don't recall the file (it had been a GCD file in all caps, that is all I know and I don't see a file in all caps any more). I will be calling support tomorrow.

My take is that it *is* a firmware thing *and* there is some way to reset the firmware.

Charging doesn't display map when charging


I learned that with the unit off - hold the on button down - don't release it. A PRE-BOOT MODE message will appear at the bottom and may flash. Continue holding down the start button. The first time I did it a series of dots came on the screen and I was instructed to touch each one. After that it started as normal. I plugged into a wall charger and but git the pc and nuvi icons again. I repeated the process - holding the on button on and let the PRE-BOOT MODE appear and kept holding but this time a different message came on and then the PRE-BOOT MODE appeared again. I let it go and took the unit to my car and plugged it into the Garmin car charger and it worked as it used to - normal. However, when I plugged it back in the house to the wall charged I got the pc and nuvi icon again. It appears that I am using the wrong wall charger as a previous writes stated. But the nuvi still worked in the car plugged into the nuvi charger. I hope this helps.
