Garmin shows picture computer

The computer picture shows if the usb cable connects to a computer. If the picture shows when the usb socket is connected to the cigar lighter power supply, it could be that the socket in the Garmin has got damaged. I had a Nuvi 200 like this where the socket had broken away from the circuit board inside, but the repair was difficult, involving micro-soldering!

Will my Garmin Nuvi 40 work with a 24 volt supply ?

If you are using a standard Garmin car charger, you can connect the charger to a DC power source that can provide between +10VDC to +30VDC. The charger produces +5VDC to power the Nuvi. This can be verified on the charger label.
You can NOT connect any voltage higher than +5VDC directly to the Nuvi.

We have 1350 Garmin GPS . How long do we charge the battery before set up.

There are 3 ways to charge your garmin satnav.
  1. You can connect it to your computer' USB port with the mini USB plug. Plug the narrow end of the cable into the back of the satnav and the USB end into the computer. Turn both on and it will charge in 8 hours approximately
  2. Connect the supplied car charging lead. Plug the narrow end into the back of the satnav and plug the other end into the cigarette lighter socket of your car for approximately 4 hours.
  3. You can also charge it with an optional mains charger which also takes 4 hours approximately.

Garmin 265WT, connected to 12v car supply, keeps going into mass storage mode then crashing in the middle of giving directions.

This happens a lot with the 2xx series nuvis. Generally the cause is that the mini USB plug on the power cord when it appears to be fully in is not. This is due to wear on the mini USB socket. Push the plug in further and it should solve the problem

I have a nuvi garmin i cut the charger to connect perment

Are you sure the wires of your car have power to them? Did you use a wire for ground or did you ground it to the chassis. Try grounding it to the chassis. Some wires may only have power when the key is on or the engine is running.

The cradle no longer charges the garmin in my vehicle. It's not charging anymore. Nuvi 750

Sometimes, if the Garmin GPS battery is allowed to fully discharge, it would require charging directly via USB cable connected to a PC or Mac before it would accept a charge for the cigarette lighter again. Try connecting this way for 4 - 8 hours or more before going forward.

Check the cigarette lighter plug in another "known good" lighter socket / vehicle to help rule out a defective socket. A socket without power indicates anything from needing to change a "simple to replace" fuse - or a bigger problem - damaged wiring in the vehicle (if the socket is used to light cigars & cigarettes - vacuum the socket out to remove ash and tobacco that may collect inside). Trying the GPS elsewhere helps eliminate possible problems with the socket. If it doesn't work elsewhere, depending on the plug that goes into the socket, it too may have a built-in fuse. Check the plug for an exposed fuse - or see if the tip unscrews to provide access to a fuse inside. If unsure, the tech Support people at Garmin are a great source for free help.

Lastly, dirt or grime on the "cradle to GPS" connection or "cable to cradle" connection could be causing the failed connection. In short - carefully inspect all points of connection and remove any deposits found.

How does one update th gps?

You connect the 2720 to your pc with the supplied usb cable.
Power up the 2720 with the ac supply cable.
Then run the garmin webupdater. It will do the update.

You must have previously installed the webupdater and the usb drivers. If you use the garmin mapsource software and can connect to the 2720, to transfer waypoints, tracks, etc., then the usb drivers are already installed.

You can download the webupdater at this site:

Hope this helps.

When i plug in to car socket the Garmin displays a black background and no directions but a lap top shown with a gas pump. What does this mean?

means its is trying to charge, and you may have a charging cir problem, try removing the battery if it has one, and then connect it to the auto adapter, you might also make sure the polarity on the adapter is correct and the proper voltage. also reset the unit with a hard reset.

Hope this helps

Garmin Gps Nuvi 300/350 stopped talking

I got a solution for this issue - buy a SPI Mini-Hi-Fi speaker - it's to be connected directly to the GPS output, there is no cord or cable, it's very light, sounds pretty well and it's totally affordable (around $10).
I've been used it for weeks, no problem at all!!!!!!!!!!!
