One of the experts here can probably give you a step-by-step based on the instructions above for you to try...

-----------------

[Edit] I'm no expert but you can try this:

1) Download the appropriate Jordan map file from:

[Only registered and activated users can see links. ]

2) Create a folder name 'Garmin' without the quotation marks onto an empty USB flash drive that's >25MB.

3) Copy the downloaded map file into this folder

4) Rename the file to 'gmapsupp.img' without the quotation marks

Instructions below are copied and adapted from the referenced instructions found at the previously provided link above:

5) Put car in run mode (with engine on or not)

6) Turn all unnecessary features off (i.e. A/C)

7) Leave your radio on (needed to recognize a USB is plugged in)

8) Goto the Navigation screen

9) Plug USB stick into vehicle, it will start Validating the USB stick

10) When the update prompts, follow the menus

11) Let the system update (few minutes process, if engine is not on, the car will shutdown half way through the process, you will need to put it back in run mode immediately, so ensure you stay with the car if you do not have the engine on)

12) It will either give a Maps updated successfully message or Reflash failed message. Just verify that the maps loaded fine, but you should be GTG [Good-To-Go].

Hope this works... good luck! [/Edit]
