When you have the GPS not in use "kill" the battery. Do not plug it in to anything just leave it on and let the battery die. When its dead, then plug it in the what ever you use to charge it. Make sure its off when it charging. If it turns on as soon as you plug it in, turn it off. Now just let it sit and charge completly. All you have to do is touch the screen and it will say its still charging or fully chaged. After that you'll be good to go. Just remember to "kill" it and charge it 100% on off once a month.
What would cause this is with all thing that need to be charged like GPS, cell phones, RC Car. When you get it the battery still has some juice in it. I know its hard not to use it and charge it up right away. But you need to first "kill" the battery, and let it charge when turned off 100%. This will keep your battey and charge lasting you a long time.

Sorry drod but you are wrong. The are lithium ion batteries, not nickel cadmium. the scenerio you are speaking of in need of a full drain and charge is called memory, and does not exist in lithium batteries.

Garmin nuvi 40 goes into usb mass storage mode when pluged to charge


I updated my Nuvi 40 with the latest software and it will not reboot into GPS mode with the usb cable connected. It used to work. I have figured out how to get it to charge with a standard USB cable:
1) Power it on.2) Press the battery icon for 8 seconds - it will enter TEST mode.3) Plug in your USB cable from the PC to the Nuvi - the screen will change to say charging.4) Press the power button 3 times rapidly - it will say Charging across the screen and it will go dim and then dark.5) To wake it up and use GPS mode while charging simply press the power button 3 times rapidly, again.
Works Great!

How do I recharge the battery on my Garmin Nuvi 255WT? I would also like to know how to update my Garmin?


Hello,

Recharging the battery is done by connecting the nuvi to a vehicle power cable in the car through the vehicle power accessory outlet or cigarette lighter.
The unit can also be charged via a powered USB port off your computer via the USB power/data cable or an AC power adapter through the USB power/data cable.

My garmin nuvi 200w keeps going into mass storage mode when plugged in to charge.as soon as it is plugged in to charge the screen appears that shows the garmin plugged in the computer. and the map...


1) Disconnecting the nuvi from the charging cable.

2) Press and hold the battery meter icon for 8 seconds. This puts the nuvi into "system test" mode.

3) Plug in the power cable.

4) Click "Exit." The nuvi should now reboot, but remain in GPS mode!

The unit will take a very slow charge via your computer. I tell most people no it doesnt charge VIA your PC just because it takes soooo long. I recommend getting a new power cable from GPSCity. Just call them up or follow the like to the cable you need.

** This cable is for the Nuvi 200 series GPS units

My Garmin will not power up.


The batteries may be depleted. Try charging via USB cable connected to a computer if cigarette lighter method does not work. When connected to a computer, the device should power on but no maps will be displayed. Disconnecting from the computer should cause the 760 to reboot - if the batteries are charged.

After charging, slide and hold the power switch for 5 to 10 seconds to power on.

Sounds like you both have a battery problem. I experienced a similar problem when trying to charge via the USB-cable connected to my computer.
Ended up buying an original charger (expensive) and the charging went smooth.
The car charger should in any case work fine, so probably your battery is not very healthy.

Try holding your finger on the battery symbol for about 10 sec. The unit will then switch to a technical page. There you can observe the battery and charging voltage. When I plug in my computer USB-cable, I read around 4,4V and that is not sufficient for charging my battery.
When connected to the original charger, this voltage rises to about 5V which gives a nice charge. When unplugging charger, the unit displays the battery capacity. If the charging voltage is OK, but battery capacity drops quickly after you unplug charger cable, the battery is probably bad. (Of course you have to charge is for some time) I think around 4V battery voltage give 100% capacity. 3,9V gives about 90% capacity.
This will not solve your problem, but can give you an idea about what is wrong.
Good luck.
