This problem usually appears when the battery is COMPLETELY DISCHARGED. So your device doesn't have enough power/energy to complete the booting cycle = to TURN ON. Take out the battery [if possible] and clean all connectors [the golden metallic tiny stripes] with a dry soft cloth. Re-insert back the battery and make a complete CHARGING CYCLE. Then try again. If the problem persists you have no other choice but to buy a new battery for your GPS device.
Common American National Standard Pipe Taper Threads
NPT - National Pipe Thread Taper
FPT - female (internal) National Pipe Taper threads
MPT - male (external) National Pipe Taper threads
NPTF - Dryseal American National Standard Taper Pipe Thread (ANSI B1.20.3)
For NPT threads a sealant compound or Teflon tape must be used for a leak-free seal. For NPTF no sealant is needed for a sealing.
Characteristics of NPT (also known as ANSI/ASME B1.20.1 Pipe Threads, General Purpose):
tapered thread 1o 47'
truncation of roots and crests are flat
60o thread angle
pitch is measured in threads per inch
Note! Pipe sizes do not refer to any physical dimensions. The outside diameter of a pipe or fitting must be measured and compared to a table for size identification. A 3/4" NPT pipe thread has an outside diameter - OD - of 1.050 inches.
Each thread size has a defined number of threads per inch - TPI, or pitch. The 3/4" NPT pipe thread has 14 threads per inch. Both the TPI and OD of the thread are required for positive identification of thread size because more than one size have the same TPI.
NPT - American Standard Pipe Thread Taper 1)
Pipe Size (inches)
Threads per Inch TPI - pitch
Approximate Length of Thread (inches)
Approximate Number of Threads to be Cut
Approximate Total thread Makeup, Hand and Wrench (inches)
Nominal Outside Pipe Diameter OD (inches)
Tap Drill (inches)
1) The taper is 1/16 inch in an inch, which is the same as 3/4 inch in a foot (angle 1o 47')
NPT threads are not interchangeable with NPS - National Pipe Straight - threads.
NPT threads may look similar to ISO 7/1 threads. However, ISO and NPT threads should not be mixed. ISO threads have 55o taper angle versus 60o for NPT. The NPT root and crest configurations are also different from ISO. For ISO threads pitch is usually measured in millimeters (may be expressed in Inch). The pitch are different.
Updating Handheld/Portable Devices
If your device has removable batteries, such as 2 AA batteries or a
lithium-ion battery pack, then it is a handheld/portable device. You
can update your device software for free using WebUpdater and a compatible cable.
Updating Fixed Mount Devices
If your device needs to be hard-wired to your boat's power supply,
then it is a fixed mount device. You can update the software by
inserting a data card containing a software update bundle into your
You have 2 options for obtaining the update bundle:
Your device freezed that is why it is stuck on the garmin screen. You need to first reset your garmin by holding the power on/off button for about 15 seconds, that way it will restart.
About the battery, when you get a new battery for your device, you need to charge it for about 3 hours before powering on, once you power on without charging it first, then it might kill the cells of the battery as they are lithium ion battery. What you have to do is to remove the battery, insert it back, then you plug it to a power source for about 3 hours, be sure that the battery is charging as the green light comes on as you plug it. If the green light does not come on, then you need to connect it to a computer using your USB cable, that way it will charge. Once it is charged for about 3hours, then you will be able to turn on your device.
First reset, then charge battery. That should do the job for you.
Hope this information was helpful.
If your garmin nuvi shuts off and refuses to turn back on, even if you press the power button, then it means the battery is weak and cannot power on the nuvi. Try to take out the battery and reinsert it back it then try to turn it on to see if it will turn on, if it does not still turn on, then borrow a battery from a friend and use it to test your nuvi, if it powers on, then your battery is either weak or dead.
Insert the battery into another gps and charge it with another charger for about 2 hours to see if it will hold a charge, try to use it to power your nuvi on to see if it will work. If it works, then it means your charger was not charging it initially. That means the charger is bad and need to be replaced, but if the battery does not turn on your nuvi after charging it for about 2 hours, then it means the battery is bad and need to be replaced.
Either ways both the charger and the battery need to be checked to know which of the two is faulty.
Carrying out the test will show you the faulty component and the solution is for you to replace it with a new one.
Hope this was helped you.
Although the WebUpdater should always be the first stop, the instructions do state that you need to have full charge to ensure you don't "brick" the unit. I've had the unit about 3 years. I already replaced one battery for this issue. I got the new battery, charged it up, and was happy. Several months later I tried to charge it up again, and got the same "Battery Missing" message. It can't be the battery! I think it's when the battery is COMPLETELY discharged the battery can't be properly detected. You have 2 choices: 1-Leave the unit on the charger for several hours. It may trickle in enough power to recognize the battery eventually. 2-The other option is NOT AUTHORIZED by Garmin, and you do it at your own risk! Find a 12v car charger you don't need. Expose the wires if necessary. Tape the positive to the contact on the far right of the battery, the negative to the middle, and nothing to the left (that's a data connection). Plug the 12v car charger in, and let it sit for a few minutes, not long or the battery could overheat. I left it on for under 10 minutes. When I inserted the battery back in the unit, it recognized the battery immediately and happily charged the battery. Long term, this is probably not an ideal solution. The voltages might not match, there are computer chips in the battery that are designed to receive power the "Garmin" way, and you could severely damage the battery (even explode?). But if it's this or trashing a $700 unit, it might be worth a try.
keep your finger in the right bottom corner when you start up the unit. it will show a warning if you want to reset! push on "YES". it will reboot the unit. (please note that you have to remove your little memory card).
