Question about Garmin nuvi 260W GPS Receiver
I GET THE ERROR MESSAGE THAT NO DETAILED MAPS SUPPORT ROUTING.
You need to unlock the unit. I had the same problem with one that I have. Try this:
The No Detailed Maps Found That Support Routing message could be due to the following reasons:

Thank you! Finding and using the unlock code restored my Nuvi 260 from a paperweight to a GPS!!

I too had this problem with the Nuvi 260w. I tried loading the new 2010
map software two times with the same result - no detailed maps found.. Those two times, while the maps were installing, I walked
away from the computer and returned later to find the installation window
The third (and successful) time, I stayed at the computer the whole time it was installing the maps to the 260w. I didn't sit and watch the progress bar the whole time, but did other stuff on the computer, and returned to the status window every so often. It completed to 100% and at the end it indicated to click on the Finish button - this "Finish" notice was not there the previous two times when I left it alone. I then unplugged the Nuvi and all was fine, the new map was loaded, and all worked well.
So I'm thinking that the installation status window probably needs some type of activity on the computer to stay alive. I also noticed that the previous two times, the img file was smaller than the third time, so the installation to the GPS did not complete the first two times.
I hope this helps someone else with the same problem.

The downloaded map file (ex: "Garmin_RMU_CNNANT2010C.exe") contains all of North America, and you must select the correct subsection (ex: "Lower 49 States+PR") that you purchased, which is listed on your Garmin myMaps page (My.Garmin.com).
I am a GPS newbie as well and selected "all of North America" when installing my free nuvi 205 map update. A mistake that's too easy to make, esp. considering Garmin still has very little info about selecting the correct map subsection listed on their support site.
You do NOT need to re-download the huge map file, thankfully, but you must re-install (30+ min) to choose the correct map subsection.
"Bad on Garmin, IMHO for not making important details like that clear to us new owners." My thoughts exactly.

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
From the Where to? and View Map page, touch the Spanner icon, settings
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.

You can download new maps..........free......................but..........
I had this problem last year with my garmin 200 and when I called they said that I was out of the 60 day time window for a free map upgrade but they would give it to me anyway. They gave me detailed instructions on how to download a new map free of charge but they didnt explain which selection replaced what I already had on mine.
As a result, I downloaded the wrong maps and have much less detail. Even though its the "2009" version, its less acurate than my old maps were. But its worth a shot, better than paying for them.
