Information on unlocking garmin maps can be found at http://www.fixya.com/support/r6197735-no_detailed_maps_found_support_routing

There's more information there than you need since the article is about garmin nuvi satnavs that display a message "No detailed maps found that support routing" but part of the article deals with locked maps. The principle is the same for the garmin Edge but you'll need to skip to the part that deals with unlocking maps.

This is an indication that the map or map unlock key is either missing or corrupted. If you have registered your unit with Garmin, try connecting to your PC and try downloading the map again. More info on missing maps can be found here:

I have 2 Garmin (205W and new 255W). I downloaded the new map update to my PC, and installed the maps onto my 255W. When I turned it on, all seemed well, but after I passed the safety screen, I got the...


It should unlock automatically.
Try reconnecting your device to computer and going onto the garmin site and get the website to check for updates.
If that fails to work, give garmin a call or send an email to them.
they are normally very quick.

Garmin Edge 705 displays message " software missing". Unit will not turn on, computer will no longer recognise that the 705 is connected by USB. I run GARMIN training centre on a MAC book.


Emailed the local support desk who said send it in!!! That means no f.....g computer for at least 10 days, what are they bloody smoking. Fat pain in the *** for us, easy for them. I have a cardiac condition that demands I monitor my heart rate and only bought this pricy tool so I could do that at night (with the backlight) when I do most of my riding. I have already sent the thing in before when it was still new and failed to power up. It was returned repaired after a week but it had lost my code for the installed, EXPENSIVE map, which I could not reload and that took another 2 weeks before I hooked up with the 6th tec contact who was able to help.
ANYWAY!
I left the thing unplugged for a few days while waiting to get organised to send it in and it reset itself and is now working-without having to send it in.....I suppose until the next crash.
Happy riding all!

Gps has lost its maps, screen says can't unlock maps


There several reasons you may receive the message Can't Unlock Maps on your nuvi or zumo device.
  • Can you press OK and get to the Where To/View map screen?
  • Did you load maps to the unit using the MapSource or MapInstall program?
  • Did you load maps to an SD data card?

If one of the points above applies to you, please follow the steps below to clear the Can't Unlock Maps message:
  1. Remove SD card from unit, if applicable.
  2. Plug the unit into your computer with a compatible USB cable.
  3. Open MyComputer/Computer icon. (Mac users skip this step.)
  4. Right-Click on the Garmin drive and select Open. (Mac users can locate the Garmin drive mounted on the Desktop.)
  5. Open the Garmin folder.1
  6. Locate a file named gmapsupp.img
  7. Right-Click and delete file named gmapsupp.img
  8. Safely disconnect your unit from your computer to see if the Can't Unlock Maps message is gone.

1. Nuvi 1100/1200/1300/1400/1600/3700 and Zumo 665 users will open the Map folder instead.

*If the gmapsupp.img file does not appear in the Garmin folder, please create an unlock file for device.

When the "no detailed maps found that support routing" screen comes up it covers any of the icons, so I'm unable to do anything.


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} The "No Detailed Maps Found That Support Routing" 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
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

"Can't Unlock Maps"


Contact Garmin regarding the unlock code as this is specific for your unit.

Cant't Unluck Maps


The "Can't Unlock Maps" message occurs when the device detects that maps have been installed, either to the internal memory or on an SD card, that do not have the proper unlock code required by Garmin. It sounds as if what you may have done is inserted an SD card with maps on it that are not unlocked for your unit. Call Garmin; they will sell you the proper unlock code for using the maps in your unit.
