SOURCE: Garmin Nuvi 610 I've lost all maps :(

If your map detail is missing, then the map information may have been disabled. To check to see if the mapping has been disabled, follow the steps below:

1. Power the unit ON.
2. From the Where to? and View Map page, touch the Wrench icon (Tools).
3. Touch Map.¹
4. Touch Map Info.
5. The unit should display the name of the map that is loaded to the unit. The box in front of the map name should have a checkmark in it. If it does not, touch the box to place a checkmark in it.
6. Touch and hold the back button.

1. Some units may require touching Settings before touching Map.

SOURCE: No Maps on My GARMIN nuvi 200W

I bought the nuvi 200w and when I registered the unit it said that there was an updated map available so I down loaded and installed it. When I turned the unit on, it said no detailed maps available and would not work. I called garmin and they said that to fix it I had to hook the nuvi up to my computer and start>my computer>nuvi>garmin there is a file called gmapprom.img (shows over 1,000,000 mb) delete this file. Open all programs>garmin>mapsource highlight the areas on the map that you want and click on the add to device icon. After doing this, my nuvi is working fine. The explanation was that the original file had files for Canada that were not unlocked. Try this and good luck!

SOURCE: GARMIN NUVI 200 SAYS NO DETAILED MAPS FOUND THAT SUPPORT ROUTING

I was having the same problem. NO DETAILED MAPS FOUND SUPPORT ROUTING & SO ON. I called Garmin this morning & I thought I would be on the phone forever with the gentleman. But I was on for less then 10 minutes. The guy asked me to connect my Nuvi to the computer using a usb cable, then asked me to go into my computer & look for the device/drive that my Garmin is using. He then prompted me to open the file that says Garmin & asked me if there was this file that said gmapprom.unl. I told him no & then he sent me the file through an email. I had to open the file & get it into the Garmin file. Then he asked me to disconnect my Nuvi from my computer & it started right up & the problem was gone. If you do have the same problem I am willing to email you the file he sent me if you would like because there is no possble way to get the file from just searching on the computer. Let me know.

SOURCE: System Software Missing on Garmin Nuvi 255W

Hi,
Take a look at this site, http://www.garmin.be/missing.html Download and unzip the software, plug your garmin in the USB and start the updater.exe program. It gets you started again. Later on you can use the Webupdater to get possible newer software..
It worked for me and my Zumo550
Goodluck

SOURCE: Is there any free map updates for the garmin nuvi?

Asmany as there are FREE dinners Updates are not free, unless you paid full price for it when you bought it. Free upgrades are a deceptive myth. If you get a free uograde its usually minor and was included in the price of the pack.
