Thread: Garmin Nuvi 55LM

If the Garmin Nuvi 55LM came with CN North America NT 2021.20 Lower 49 States you will have to buy the Garmin - City Navigator North America NT 2021.20.
You then get an unlock key so it will work on the 55LM

Cost $99.99 USD if you go over to Canada a lot.......

Spoiler: This come with Canada and Mexico

I do not think Garmin - City Navigator North America NT 2020.20 even if it is unlocked will work on the 55LM.
You will have try and see.
But you should know all this with all the Garmin units you have had.

Try reading these posts on the 55LM.
