Summary
Business Navigation (HU Basic) - not possible to downgrade the navigation map. After replacing the HU Basic (Entry Navigation), the version of the navigation map cannot be downgraded to the version of the replaced HU Basic. This is caused by an error in the routing table which is stored in the Central Gateway Module. Therefore, no communication with the map server can be established.
