    I lost all of my favorites and the map doesn't seem to be working. Nothing in the city I live in. Just shows some major highways and nothing else.

  • Anonymous Dec 10, 2008

    After using the device (Nuvi 200) for three months, the thing froze and a "no detail map found..." window appeared on the screen. If you press the screen for a while the box will disappear and a map with no streets will show... but: the actual 2008 2009 city navigator map from garmin was lost, so did my favorites and other stuff. The device was never plugged into a computer before then and Garmin technicians say that I had to physically delete the map from my nuvi using a computer, they don't believe the thing just disappeared! i hooked it up to the computer and it's hard-drive shows about 1.7 GB of free space, the MAP WAS GONE! I had to call Garmin customer service and download a new map fro three hours! still this thing doesn't work!

    Turned on my Garmin Nuvi 205W and wont load because no maps

    I also had the same thing happen to my Nuvi 250W. I drove all the way to Seattle, WA and it worked great. Keep in mind I have never pluged it to a computer - ever. Upon turning the car back on the gps came on as usual but with limited map detail. I turn the car off and then back on and this time it shows the screen saying no maps found and that it cannot work without them.

    If you lost the detail in your maps, make sure you have the City Navigator box checked. Click on the Wrench, then the Gear and then Map, then map info.

I lost all my maps on my Garmin Street Pilot C330. I contacted Garmin support and went through a number of steps with them including a master reste to no avail. My unot was not being detected on their website and I couldn't register it or access "My maps". All the while I was trying to fix this I was indoors at my desktop where my unit would lose satellite reception. I took my laptop computer and unit outdoors where I got satellite reception. Loaded the Garmin USB drivers and Communicator program on my laptop. Turned on the unit, let it attain satellite reception, plugged it into the computer w/ USB cable and bingo! The unit was detected by the Garmin website. I was then able to register and access My Maps. I downloaded my maps to the unit, which in all took about an hour to complete. Problem solved.

SOURCE: Garmin Nuvi 660 lost Europe maps

Eventually managed to speak to a man at Garmin who confirmed that it was not loading any European maps because it didn't have enough spare memory to load them all. He said that he would email me instructions for freeing up sufficient memory, the email never arrived but I decided to delet all the voice languages that were no use to me and all the other language 'help' files and tried again - it worked.
At no point did I get a 'insufficiant memory' warning, which would have been very helpful, nor is there any guidance for how much memory will be required when embarking on the update. Take note Garmin...

SOURCE: I need to update my

Go to and type in the serial number located at the bottom of the gps system. There is a one time cost of $69.99 for the update, which is a bit pricey.

My understanding is there are no free maps and anyone using or offering one is liable for prosecution. The use of unpaid maps is Piracy and not part of this forums brief to supply them or point one in the direction to where pirate software may be offered.

Most times the maps require an activation code which is part of the licence code issued with your GPS and the Map being purchased.

Many companies are now applying security tags to maps that when operated lock the unit so it is dysfuctional and has to be sent to the manufacturer to be unlocked for a fee + the licence for new maps, so beware

SOURCE: need free updates for my garmin nuvi 200

You didn't say how long you've had your device, but if you haven't registered your device at yet, go do that and they will then offer you a free upgrade.

Other than that, I don't think you'll find anything free. The next best thing is to buy the "nüMaps Lifetime™". I felt this was the best deal they have.

Can you change a GPS navigation system from street name to postcode

I am not sure what you mean by " post code" but a gps uses maps that are stored on the unit itself. In order to make a change on how it shows locations, it would mean that the maps would have to be edited. Any change like you are suggesting would involve a lot of work with computer programming. Since it is not a standard method of locating, it would not be marketed.

I have a garmin nuvi and the cable that you put into your cigarette lighter will not work. I changed the fuse and it still will not keep the unit charged. I can charge it on my computer with a usb cable....

Do you see a lightning bolt symbol over the battery bar graph? This indicates that its charging. If it's under warranty, please contact Garmin on their website. and call them. No need to worry about this if its under warranty. Send them your charger too.

Missing bluetooth software

The 300 does NOT have bluetooth. See this Garmin link:

The 360 has bluetooth. In order to have bluetooth, you must have the main board inside that has the bluetooth circuitry AND the firmware to support it. The 300 does NOT have the circuitry for bluetooth.
