I have an unused garmin topographical data card of the western united states. It costs $100 new, i got it but cant use it. It shows up to date hiking trails, roads, off-roading routes, etc. The SKU is 1441649 if you have any questions let me know! It is a microSD card with an SD adapter.

here is an image https://imgur.com/a/j52xUw7 - the product is unopened.

I dont have anything particular in mind for a trade, i am quite fond of knives so make an offer with what you have but cash is king.
