The original message of "No detailed maps to support routing" is typically caused by a missing or corrupted map file. It can also be caused by not having the proper map unlock key installed on the unit.
If that problem has been resolved and you can't obtain an address when setting a route, make sure that the map is turned on.
Go to settings, select the map icon and then the map info button. Make sure there is a check mark in the square next to the text that lists the map that you have installed on the unit.
If the map info button is grayed out, then you still have a map issue.
If the square does not have a check mark in it, press the square to place a check mark in the square. This will activate the map.
With this unit, you can put several maps on it and you can select which map will be active or inactive with the check mark.

Mine says no detailed maps in memory but when I look at it on the PC all the files compare with the backup I took. Even overwriting them does not help.
I have exact the same problem since yesterday with my Streetpilot c510
I've got the same problem, was working one day then the next it says 'no detailed maps found that support routing...'
Yes - I also get the notice 'Can't unlock maps' ......one day was working fine; this next I have this problem
Please let me know what I need to do to fix this
Thanks

Bought Garmin Nuvi 250w today. Initially it was working fine. A couple of hours later a message appeared when starting up - "No detailed maps found that support routing. The nuvi cannot be used without them.", and it can't be! The screen just locks with the message displayed - even after reset. Does anyone have a solution to this problem????
I have the same exact problem with my Garmin 200 and hey, can you stop putting people with the same problem under "solution" it's kind of misleading.
my garmin nuvi is saying no detailed maps sopporting routing & i just started using it.
