How do i open garmin 250 to replace battery? Will not hold a charge while driving

The Nuvi 780 is an older GPS. Most likely, the battery needs to be replaced due to age. Many lithium-Ion batteries are only good for 2 years. More information can be found here:

http://www.sharc.net/gps_battery_repair.htm

Please have the battery replaced by a professional. We have repaired many units from failed battery replacements by customers. Often other things get broken in the process, sometimes beyond repair.

Do not open the nuvi, the garmin site recommends the following method instead:

1. Make sure you are sliding the power button all the way to the left.
   • If the unit does not respond, it may be that the battery is not charged.
2. Connect the nuvi to a power source such as the USB cable and your computer.
3. Reset the device, if the problem persists, by sliding the power button to the left and holding it in that position for 10 seconds
   • This resets the unit and prompts it to power on

If this fails to solve the problem, contact "SUPPORT" at www.garmin.com.

Please rate this reply if helpful - good luck.

It will shut off right away if the batteries are not charged.

Please charge the unit with the vehicle power cable or on a computer for at least three hours. After charging the unit, it should power on and function normally. If the unit will not charge in the vehicle, check the fuse in the power cable for the unit and the power outlet in the vehicle.
The nuvi 200 series, 300 series, 600 series, 700 series, 1000 series and the StreetPilot C300 and C500 series do not have user replaceable batteries. These units must be sent in to a Garmin approved repair facilities if a battery issue arises. Garmin and Raytech are the only Garmin approved repair facilities. Raytech is a repair facility for Canadian customers. To repair your device please contact the specific repair facility for your region. If your device is not still under the 1 year warranty, there will be a cost associated with the repair of your device.

There are two types of leads that you can buy.

The one supplied with the Garmin expects you to plug the GPS into the PC via the USB and if you use this to try and charge your Garmin in your car it will think it is connected to the PC and show the connection screen. it will charge the unit but you can't see the map.!!!

Make sure that you buy a lead specially for the Garmin for use in the car its the only type of SAT NAV that you will have this problem with.

LOL

Is not wery hard if you have tools to open .

Try here for battery www.satnavservice.com

if ther battery went totally flat place it on charge for an hour or so to revive it. Max battery life in storage is 4 days with a good battery.

Charging it even tho the charge light may not show should build up enough charge to eventually show the light and allow you to turn it on. It should remain on charge for 5hrs.

Other possibility is a collapsed cell in battery, replace the battery

if the greens bars on the upper right indicates fully charged

HI,
I have the problem solved I at first had this problem after about 5 minutes of messing with my GARMIN NUVI and having many electronic gadget I thought about diffrent buttons to hit at the same time heres how you charge your NUVI with a computer and a usb cable

1st: make sure your NUVI is OFF then plug in the usb cable from the computer to the NUVI, after you hear your computer ding from new device connected, and the NUVI displays the computer icon move to step 2

step 2: if you have xp go to START and MY COMPUTER. with vista its START then COMPUTER button on the right side

step 3: with MY COMPUTER window open hold the NUVI power switch to the ON position and RIGHT CLICK the NUVI device logo (blue triangle) and select EJECT .. ( DON;T HIT SAFiLY REMOVE)

step 4: when you see GARMIN display on the screen you can letgo of the power button on the NUVI ****** if you unplugthe usb it will display message stating EXTERNAL POWER LOST SWITCHING TO BATTERY POWER***** while it is plugged to the computer the battery meter will disaper

Common issue. Steps to troubleshoot/solve:
1. Pull off face, press reset tab.
2. If unit wont turn on or if turns off immediately, connect to home computer using mini usb on side of gps (any usb cord that fits will do). This will charge the internal gps battery, which is discharged.
3. You will not be able to see the gps charge indicator while the usb cord is plugged into the unit. To check charge level, disconnect it, turn it on, and note the large "battery" icon.
4 Do you have a dead internal battery? If the gps holds a charge from your computer usb port, you don't.
5. If you have a dead battery, Google DIY replacement. With some soldering it can done for $15 total.
6. If you don't have a dead battery, the issue is charging from the cigarette lighter socket. Your car socket may have blown a fuse (check car manual). Your charger unit may have blown a fuse (unscrew the tip, check fuse inside). Also, some car sockets don't work when the ignition is off. Test yours.
7. There is a good chance the connection of the charger wire to the gps cradle is the problem. Fiddle with that. Replacement cradles are available for the c340 at about $25.
8. If your unit is not charging from the cradle/socket, buy a 12v usb cord. Plug into socket and into usb port of the gps. This is a workaround or alternative to buying a new cradle.
9. IMPORTANT: observe the "battery" icon while driving, esp. if you have doubts about charging. Basically, if you can see the icon, you're not connected to an outside (car or computer) power source. That is, if you can see the battery-charge indication, it means your battery is currently discharging and unless you get another power source to work it will be dead in a few hours.

"my garmin c330 will not charge in the car while traveling?it has a full charge when i head out but after 4 hours it shows low battery,i was thinking the gps was supose to charge with the car adapter plug in.my will not charge."

There is a problem with the cable or the cigarette lighter power supply. If the cigarette is working then when you start the car the Garmin should turn on and when you turn off the engine the Garmin should shut down. If you are manually turn the unit on/off then it is not running off the cigarette lighter power supply. Check to make sure there is power coming from the cigarette lighter.
