Ok, you will need to have Garmin Express running on your computer. If you don't have it, you can download it from HERE.
Install and run it on your PC and then plug in your Nuvi. Garmion Express will pick it up and give you a list of update options including maps and software. Just follow the prompts. Not that it can take about an hour for a full map update,Please let me know if you need help at any stage of this update. If not, please rate the service you received today (3-5 stars) so that I can be credited with helping. It does not close our dialog together and we can continue at any time.Regards
