    Please do not try to open your Nuvi... unless you have the right tools and experience... you risk damaging it where it may not be repairable. Please see this link:http://www.sharc.net/gps_battery_repair.... andhttp://www.sharc.net/gps_charger_repair.... - Jim

When the garmin is pluged into the lighter it will not charge but says to connect to computer. while pluged to computer it will charge


It sounds like your Garmin Nuvi is stuck in "computer" mode. Try resetting it. Here's how:
Without plugging it in to anything, turn it on. Open the GPS antenna and look behind it for the "Reset" button. Press it firmly. It should restart. Then try it in your car and see if that solves it.

If that doesn't work, try reinstalling the software. To do that, plug it into your computer with the USB cable. Then go to http://www.garmin.com
On the web site, first register your product if you haven't done that yet. Then look for "Support" and follow their instructions for updating your software.

A third possibility
is that your car adapter is bad. Try replacing it. (Try this after the first two ideas because you'll have to spend some money, and this might not solve it either.)

Good luck.

My gps is not turning on. I tried to charge but there is no signal. Can you please help me?


A Garmin Nuvi 1300 that won't start, or is acting erratically is symptomatic of having corrupt firmware.

To correct this, I recommend backing up your favorites, clearing all user data, and if it still is stuck, then updating your Nuvi firmware.

Follow these three steps to take to get your Garmin Nuvi 1300 running like new:

  1. Back up your Favorites.
  2. Perform a Hard Reset.
  3. Download and then run Garmin WebUpdater to replace its firmware / system software.

I hope that helps.

No maps on garmin nuvie 200


You will have to send it to Garmin with the original receipt and see if they'll reload the maps the unit came with. There may be a charge for this.

Garmin nuvi 660 frozen


I did connect it to the computer via my USB cord - a Garmin menu came up and after opening a couple of the choices the Garmin was workable again. I don't really know why. But all is good here.
