Question: What should I do if my Garmin nuvi or zumo displays the message "No Detailed Maps Found That Support Routing" or "No Map Data Available?"
The "No Detailed Maps Found That Support Routing" or "No Map Data Available" message may appear on your device for the following reasons:
The GPS device is missing it's unlock code
The maps on the GPS device have been disabled
To determine the cause of the message, touch the screen until the message "No Detailed Maps Found That Support Routing" disappears.
If you see a "Can't Unlock Maps" message following this error, remove any microSD / SD cards in the device and follow the instructions below for Retrieving your unlock codes followed by the instructions for Creating an unlock file
If you do not get the Can't Unlock Maps message then skip to the instructions for Enabling maps on the GPS device
Call up Garmin and have them walk you threw a trouble shooting procedure. It sounds like your unit has erased itself by no fault of yours. Garmin will replace it once you get ahold of them. There is not anything that we can do without thier support.
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.
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.
