No detailed maps found that support routing


Please connect your Nuvi up to a PC and look to see if you have the map file "gmapprom.img" in the Garmin directory. The file should be around 1.5 to 2 GB in size. If the file is missing you will need to replace it. If you have registered your unit with Garmin, you may be able to log into your Garmin account and download the map file again. If you can't, then you will need to send the unit to have the map file restored by a service shop. More info on missing maps can be found here:

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
(Tools).
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.

No detailed maps found that support routing.


You're unit is probably missing the gmapprom.img file (failed update maybe?).

Try contacting Garmin - if you've got registered maps they may send you another copy (although big file - 100+MB)

Route problem


If you don't have "Detailed Maps" for the area you are travelling in, it will not have adequate map detail to create routes that are not on major highways.

To remedy this, you will need to use another of GARMIN's products... I believe it's called Mapsource City Navigator, and will have to be purchased for the area you are concerned with. This PC software will then allow you to load additional Map Data onto an SD card, which will slip into the slot on the left side of the unit.

You can find out about it at their website www.garmin.com then look in Maps
