From the Garmin web site:
Question: What should I do if my Garmin nuvi / zumo displays the message "No Detailed Maps That Support Autorouting."?
Answer: Please follow these steps to troubleshoot the error message:
Checking the unit:

1. Hold your finger down on the screen until the message "No Detailed Maps That Support Autorouting" disappears.
2. If you get a locked maps message following this error please remove any SD cards in the device and skip down to the instructions for "Getting your unlock codes".If you did not get a locked maps message then please select tools>settings>map>mapinfo button.
3. Check the box next to the mapping product City Navigator and you should no longer get the "No Detailed Maps That Support Autorouting" message.

It is possible that problem may have been created because of the way Map subscriptions work. I'll verify but my latest theory is that you may have to unlock every update not just the map set. I have 4 Garmin GPS units, all 4 units use the same map sets (City Navigator - North America), and I have 4 City Navigator Unlock Codes. Plus I have 2 City Navigator Map Subscriptions that provide quarterly updates. Keeping track of Update Codes is a PIA. It is possible that each quarterly update also needs to go through the Unlock process. Apparently MapInstall doesn't do that automatically. Here are Garmin Instructions on How to unlock Garmin maps. If I am reading correctly, You have to manually add the update code to MapInstall every time you get a Quarterly Update.

This could have been done in a much more User Friendly Way!!!
It is more than a little disheartening to call Garmin Tech Support because the standard greeting seems to be "your expected wait will be over 30 minutes". That would send me to web site but I had already been there and saw no information to help with the "Maps Can't Unlock" error that was driving me crazy

Yes. There is one more mapset and then there will be no more for us using the StreetPilot 2620. You are looking for the disc set North American Navigator 2009. Make sure you do not purchase the NT version. I found the item on EBAY for $81and purchased it and it worked just fine. The 2009 is the last compatible map set that Garmin released for the 2620. Be certain that what you purchase includes that unlock key otherwise you will spend another $75 on that at the Garmin Unlock Site.

Here is the link that is good for a few more days, however, may relist it. The seller is yumelectronics and the search term is 2009 City Navigator.

Here is the search for EBAY:

Here is the item on Garmin's site:

Listed as:

It is $99.99.

Good luck, and let me know if you have any other questions.

• 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

Retrieving your unlock codes:

1. Log into your myGarmin account
2. Select myMaps
3. Select Manage Maps
4. Select the device from the drop down menu
5. The unlock code is located under the "Maps installed on this device" section

sounds like you might not have the new map set selected

settings -> map -> map info (make sure the NT 2009 map is checked)

Did you get this figured out?

Are you trying to update a Nuvi that already has European maps installed or are you trying to install European maps into a Nuvi that does not already have them?

If it's a map update, are you getting the error when you download the update to pc, or when you are trying to install the update to the Nuvi?

When I install US map updates into a streetpilot or Nuvi, it typically ends with a download error but the maps do in fact get updated and the new software versions are shown in the setup menus.

The Garmin rep I spoke with says that is normal.

If you are in the United States, I can get you maps, updates, and even install them for you if you wish.

Feel free to shoot me a message if you're interested.

I found a telephone number for Garmin Support. I've now resolved my problem. Thanks.

Connect it to a PC and delete the map(s) using windows explorer.
