Thread: Need Info about USA/CANADA Maps 2017.Q1

You can not select any device. (that is, you can, but...)
They'll demand the serial number of the device and the previous registration. That part you seen is strictly for standalone devices.
So, as Android user, you can download only legal NextGen from Play Store, and maps that are legally offered along with it. I don't know which version is current for USA, but for Europe users are complain that get a very outdated version.
Btw, when you purchase legal maps, you get a legal license (refers to standalone devices and others). The type of license depends on the package you buy and the types of software that is on the device. Therefore, there are incomplete licenses to which the users of the forum complain

It's not nice to say, but as Android user, it is better for you to download some software from forum, and content you need.
If you really need latest maps, and money is not a problem, then look for your market which are popular devices, that receive the freshest regular updates. Buy that device.
