Updated today are the HERE trio of applications for Windows Phone 8, principally with the inclusion of support for a generic HERE account and the possible migration of your existing Nokia account-synced 'favourites'. In addition, there are new countries available and Drive+ is apparently now free for all, i.e. voice-guidance in real time for all (supported) countries for all users, regardless of device. 

From the HERE blog:

Today’s update of HERE Drive+ for Windows Phone brings voice-guided navigation for 18 new countries and territories: Algeria, Angola*, Bangladesh*, Burkina Faso, Côte d’Ivoire, Cyprus, Iraq, Libya, Mauritania, Mauritius, Nepal*, Paraguay, Saint Helena, Senegal*, Sri Lanka*, Suriname*, Zambia*, Zimbabwe*. This brings the total number of freely navigable countries to 118.

Additionally, we have updated HERE Maps, HERE Drive+, HERE Transit, HERE City Lens for Windows Phone, and HERE Maps for Windows 8.1 will soon follow. This brings a range of stability and performance improvements across all the apps and we have made HERE Transit and HERE Drive+ free not only for all Windows Phone 8.1 smartphones but also for Windows Phone 8.0. With the update, the apps will use the new HERE account to keep your Collections in sync across all HERE-powered devices and the newly reinvented here.com.

Migrating to a HERE Account on Windows and Windows Phone 8

One of the most loved features of HERE applications is the ability to keep your Collections with you across screens and operating systems. The first time you launch the updated application, you can move your Collections to the new HERE account in a few simple steps.

• After accepting the terms and conditions, you’ll be prompted to sign in or to sign up to create a new HERE account. From now on, HERE apps will use the HERE account, so we recommend creating an account to share your favorites across your devices and keep them safe in the cloud.

• If you’ve only used HERE on Windows or Windows Phone, then you probably haven’t had the chance to create a HERE account yet. You can easily create a one now using an email address or your Facebook details (we will not post anything to Facebook without your permission).

• If you are logged in with your Nokia account on your tablet or smartphone, the app will ask if you wish to import your Collections. You can keep using the app right away, and you’ll be notified by email once the migration is completed. It might take a few minutes depending on how many places you have collected.
   
   

 

As usual, just update your HERE Maps apps in the Windows Phone Store (use settings/check for updates, etc.)

You can also start the import process later within the application or complete it on here.com. But, because Nokia accounts will soon be discontinued, it’s important for you to migrate your Collections (of favourites) now.

Don't worry if you don't want to create yet another account - as mentioned above, HERE also works with using Facebook (via OAuth), so just plug in these details and you're done. The import process takes place in the background and needs server involvement and capacity, but an email arrived within a minute for me, to say that the migration had been completed.

NB. Of the new countries mentioned above, not all the roads in them have been mapped yet. In such cases, mapping works but full navigation may not.
