First, check to make sure the map file is there. The file name is gmapprom.img. It's located in the Garmin directory. It should be 1GB in size. To do this you need to connect the Nuvi to a PC with a USB cable.

Next, please tell me what year of map you have on your unit, 2009, 2010, etc.

Them, email me your units internal serial number. Its a 10 digit number (not the number on the outside). The number starts with a "3" and can be found by pressing the tools button, then system and then "about".
