Try connecting it to a power outlet and check it turns on. If does then the replacement Battery is faulty. Once connect to power outlet check the battery connection from the GPS if they give out any power (You will need a multimeter to check). If the is power coming out from the GPS to the battery connection then the battery is the problem, Make sure to check the battery too. If it works or no.

Hope that helps

My nuvi 260W displays the computer plug in sybole then turns of both while move and sitting still an d is connected to power supply. I have bought new connector for power supply.

Whenever you see the computer to GPS symbol pop up while using the DC car charger, this is an indication of a loose USB jack (bad connection) between the jack and the printed circuit board.

You should only see this symbol when connected to the PC using the USB cable. You should never see it when using the charger. Please see this link for more information and how to have it repaired:

Please ensure that the device is receiving a charge while it is connected to the vehicle power cable. If the battery is receiving power from the vehicle power cable then the battery icon (located next to the time) would disappear from the Main Menu.
If the unit does not power on while attached to the vehicle power cable please follow steps from below to perform a soft reset:
  1. Connect the device to an external power source1
  2. Slide and hold the power key to the on position for 15 seconds
The device should power on.
  1. Preferably the vehicle power cable or a USB cable from a computer
  2. Some of the older Nuvi 200 series will have a reset button on the bottom of the device. It can be found on the bottom of the device on the same sticker that the serial number is printed on. It is a very tiny button and hard to see. So look carefully!!

Press the Power button on the top right corner of the case.
If unit will not power on, battery may be dead. Try connecting car charger or power adapter to unit.
To charge battery faster, leave unit connected to power adapter or car cord. Press and hold Power button to turn unit off. Screen will show "Going into charge mode."

Doesn' t turn on

1. Connect the TomTom to the USB for power (green light should be on).
2. Hit the reset button on the bottom of the device - you should feel it depress slightly.
3. Press firmly and hold the power button and count to 10.
5. Try this a couple of times if it doesn't work the first time.

Even if your battery is ****, the power connection has a pass-through, so you can still use the device as long as its connected to the charger.

Make sure that the bike's electrical connection to the GPS unit is actualy not having power once you turn the key off in the bike. This GPS turns on with external power. It is inherent in to its design.

In the case were you cannot have the bike's power source to the GPS turn off with the key, see if you can wire a small in-line switch in series with the GPS unit so that you have an external power switch. This should be easy to do.

The models I have used from Garmin have their own power switch. You should be able to use its power switch to turn it off.

Keeps turning off

Your power cord is cutting in and out. You either have a bad power cord or there is something wrong with the connection to the cigarette lighter. When the unit say "Running on battery - will turn off in 30 seconds" this mean that it has lost external power. This is by design so that when you shut off the engine external power is cut to the unit and that it will shut down.

It a shame that for the C330 Garmin decided to remove the LED light from the power cord that shows the power cord is connected correctly to the cigarette lighter.
