Transferring address book from phone to Navigator via Bluetooth

If you transfer the address book from your Bluetooth enabled phone to the Hema Navigator, you may find that either the names, or numbers do not transfer correctly. The content may be garbled.

Address book transfer is not necessarily supported by the Navigator from all phones.

Different manufacturers do not always support the standards (or they support the standards "in their own way").

Sadly, there is not much you (or we) can do about this...
