Look under the top right hand menu on your app:

Go to Manage Maps.

You will a section in orange: Maps and Guides Available: there should be an option to restore your previous map purchases on this APP.

It his does not work, reset your entire phone by switching it off and on again and try the steps above again.

A customer previously reported to us that he had the option to restore the purchase, but after choosing that his entire screen went grey. It turned out to be a technical problem with his phone and not our APP.

We suggest you try and use a strong internet connection and rather a WIFI connection if possible.
