Re: help no display

Cheers I had the same problem. My Garmin was just under 2 years old and stopped working, I pressed the reset button and now it works fine. Garmin wanted to charge me £75 to fix it.

Sounds like they are designed to stop working after so long!
what a rip off!

Re: help no display

If you pull off the front outer surround trim panel (prize off just underneath the garmin logo) you'll find a reset button. That should fix it for you.

I bought Garmin nuvi 250 in Thailand and it works well. However, I brought it to London and try to use it.. It always show "unable to calculate route: no roads near starting point". Moreover, the screen...

It's possible that it doesn't have a map of England. Press Tools, then press Settings then press Map. Press Map Info. This will show you the maps installed on your satnav and the map selected should have a tick beside it. If there's no map of Europe or UK on it you'll need to buy one. If there's one there but not ticked press on it and it will become selected and should work fine then.
If you need to buy a map you'll need to register the satnav if you haven't already done so.
Connect the satnav to your computer and go to Select your country. Click on myGarmin and then on Register Your Garmin Device. Follow the prompts. You'll be asked to create a username and password. Keep them in a safe place as you'll probably need them again to update maps.
Log into myGarmin and click on myMaps.
Click on Shop fFor More Maps.
Select the one you want, UK and Ireland or W Europe would do. Follow the prompts.

I have a Nuvi 250W and just downloaded new maps from Garmin (bought the online lifetime option). Now I only have the major routes on the display. I seem to have lost the minor roads? How must I fix...

First press tools, then settings and then maps. Press map info and the name of your map should be displayed with a tick beside it. If there's no tick press the map name and a tick will appear beside it. The map is now selected and should be ok.

If that doesn't solve the problem it may be because the map is locked. To unlock the map follow the instructions on and that should solve the problem.

The problem of east/west may be solved when the map is sorted out. If not change the voice. Press tools, settings, language and the voice name and select another voice. If there's not another english speaking voice you can connect your satnav to the computer and open webinstaller. When it finishes checking for software updates it will give you the option to download new voices. Tick the ones you want and then press next. They will be downloaded and then when you have disconnected from the pc go through the process of selecting a new voice again.

I tried to update my new Garmin Nuvi 255w. It now reads as follows, No detail maps found that support routing. The nuvi cannot be used without them. I have a ABI and to help me even to get home is hard....

There are 2 possible reasons for this. The most likely is that the map is not selected. Go to Tools, Settings, Map and press Map Info. Is the map ticked. If not press it and it will tick. The map should then work.

The other reason is that the map may be locked. The instructions for unlocking the map are at

Garmin nuvi says, "no detailed maps found to support routing."

I am very sorry to hear that you are having problems with the unit. You
may need to switch the unit on and press and hold the centre of the
screen until the message ?No detailed maps? message disappears.

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:

From the Where to? and View Map page, touch the Spanner icon, settings
Touch Map.
Touch Map Info.
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 tick in it. If it does
not, touch the box to place a tick in it.

Then please test by searching for an address.

Contact Garmins Tech support hot Line they will walk you through the process and if they can't fix it over the phone they will send you a disk that will completely fix the "NO detailed maps found that support routing" I have contacted them with the same problem and the disc was free of charge.

"No Map Data Available" - Garmin Nuvi 350

This is because your map file has either been deleted or corrupted and needs to be replaced. Please see this link for more info. Too much info to copy & paste here:
