Hello & Welcome,

I see that you have responded to your first answer with a "bad service" rating, and at 14+ hours after the answer was offered. I can also tell that you may be a bit frustrated by the process here, and for getting maps of North America for your unit.

Please let me explain a couple of "options" that you have for getting North America maps, and which one you pick will depend on your situation, and your plans for using this unit now and in the future.

First, you CAN get maps for North America for your unit. Also, you can get them in different "formats". That is, you can get them in the form of a download, on a DVD (for transfer to your unit from a computer), or in a "preprogrammed" microSD card.

For easy installation, the microSD card would be the choice I would take. This is because the microSD card is programmed with the latest maps of North America - at the Garmin facilities - and then shipped to you so that you can install it in your unit. You would then install the microSD card in your unit, power your unit up and then "enable" the map on your "map info" screen (by putting the "check mark" next to the file name). One more reboot, and you are off and running. No worry about making space for the new maps, or having to delete anything from your unit.

Now if you want to get downloaded maps (which can really be a bit of a pain to manage), you can select the "download" option at the link I have provided below.
BUT ... to keep from having to delete any files and to keep the current maps you already have, I would HIGHLY recommend getting a microSD card of 4GB or 8GB capacity (readily available in ANY store that carries GPS units, digital cameras, etc. - about $15 USD or less) and installing in your unit FIRST. Then when it comes time to do the download and installation of the maps, you will want to select the SD card as the destination of the North America maps. You will also want to make a selection during the installation of "Install to device and computer", so that the files will be SAVED on your computer and can be transferred to your unit at a later time - if needed.
--------------- Did I mention that this can be a bit of a pain? This is what I mean when I mentioned that I would choose the microSD option. ---------------

Now if you want to purchase from that link, make sure you select the correct radio button, to select the option you want (download, microSD, or DVD), make sure the screen updates and shows that the button you want is ON (selected), and then click the Add to Cart button. Then go through the purchase process to get your maps.

Now, here is the part about "your plans for using this unit now and in the future" I mentioned earlier.

Big Picture:
1) If you are planning on returning to Europe and using this unit there, I recommend NOT deleting any of your current maps and putting the North America maps on a microSD card (in whatever form you like - preprogrammed or download).

2) If you are NOT planning on using the unit in Europe again, then there are other newer models that may be a more cost effective and reliable unit for you. This is because the Nuvi 860 is a discontinued unit (no longer made, out of warranty), and the newer units have dropped in price dramatically in the last year or so. As a matter of fact, many of the current units on the market come with lifetime map updates, which you had to pay for (each year) in the past, if you wanted current maps.

So when you compare the price of just the maps that you want to get (~$80) to the price of a newer unit (search Amazon for current "street" prices), I'm sure you will discover that a new unit, with all new hardware and a 1 year warranty, will be less total cost and more reliable in the long term then it would be if you get North America maps alone for your unit.

There are other factors involved, such as features that you have and use, and they all have to be weighed in the decision, but that will be your decision and I can not make it for you. I am just trying to lay out the options for you so that you can make an "informed decision". I am NOT a salesman, and I make no commission on a map purchase or new unit purchase.

Now I have one other item for you before I sign off for the night - which is a "map update guide" - so that you can get an idea of the steps involved and the different methods of getting map updates. It is in PDF format, and is 4 pages long, and I recommend that you look it over before making your final decision.

I hope this helps answer your questions.
