    After trying for hours to start this unit, including attaching it to another mount in another auto without luck. Then this AM while the unit was on my desk, unplugged I happened to press the power key and it started?????
    I will accept this solution even though it was not a result of anything you or I did. Can't understand what might have happened. Do you have any other idea for this problem? Thanks.

Hi,

Please perform this below steps to isolate this issue.

  1. Plug the nuvi into a powered on computer using a USB cable.
  2. The nuvi should power on when you plug it in showing a computer plugged into the nuvi on the screen (mass storage mode).
  3. If the nuvi does not power on, while plugged into the computer press the reset button located under the antenna on the back of the nuvi.
  4. Allow the nuvi to set and charge for a couple of hours.
  5. Once charged take the device to the vehicle plugging the vehicle power cable into the vehicle and into the back of the mount the Nuvi sets on. Place the Nuvi on the mount
  6. With the power cable plugged into the vehicle and the vehicle powered on the light on the cable should light up.
  7. You'll know that your nuvi is receiving power by looking on the main screen next to the time, the battery icon will have a lightning bolt through it. You'll also be able to power the nuvi off and see dimly light on the screen "charging battery. Press the power key to turn on." If the light does not come on check the fuse located in the tip of the vehicle power cable.
  8. The end of the cable unscrews to reveal this fuse. Check to make sure the wire element inside the fuse is in contact and that there is no discoloration. If you see either of these the fuse needs to be replaced with the replacement fuse specifications listed on the sticker attached to the cable.
  9. If the fuse looks good and there is still no light the vehicle power outlet may need to be checked to see if it has power.
Let me know the Result...

Regards,
Suraj

Try to use another Garmin AC adapter or your computer to charge the unit overnight and see if the battery will take a charge.
If recharging doesn't work, then your only option is to replace the battery. If the unit is still under warranty, then call Garmin for a RMA. Garmin charges $175 for battery replacement for out of warranty.

    hi there

    i just talked to a friend of mine that works at gps works in cali and i told him of this problem and he told me that they have a internal reset device that will automatically reset the unit after any where from 15 minutes up to 2 hours depending on the unit it takes this time for the unit to relearn itself so when you were trying to keep turning it off and on it was not letting it'self relern the system he said this is normally caused by the unit being unplugged while the unit is still on or a temporary loss of power to the unit i hope this is to some assistance to you for the future

Used my garmin edge 305 today on the ride, it worked fine, powered off after the ride. Got home turned on to review my stats and then powered off and went to upload and wouldn't upload, so tried to turn it...


Edge 205 or 305 often crash, then impossible to power on again.

Here is the way to reset the Garmin edge :

Soft reset : hold mode and lap/reset buttons for 10 seconds
Hard reset : device should be powered down, hold start and mode buttons for 3 seconds then pulse press the lap/reset button.

After soft reset, you need to hold start button for up to 10 secs before it starts.

After hard reset, you will loose all your data, including profiles.

White screen


The LCD display is defective and needs to be replaced. Your touchscreen is probably OK, unless its been physically damaged.

The touchscreen can be salvaged if OK.

Issues with new Garmin


Try pushing the reset button and charging again. If that doesn't work I think you've got a defective unit. Contact the seller and sendit back for a trade.

Connection


use a cassette adapter. put the adapter in your car's cassette player and plug the wire into you garmin. when a command is made, it will play through your car's stereo, provided it is on the cassette mode. also, using the cassette adapter, you can play music from your nuvi if you have music loaded onto a sd card and placed in the nuvi's sd slot. the nuvi will interupt the music to give directions, then go back to playing music.

I had the same problem recently... What I did was open the front casing and hit the reset button under the cover, then it turned on while plugged into the car adapter.
