Nokia Navigation Pack LD-2
This enhancement includes a GPS receiver you mount in a car and a 
navigation software that you install in a mobile phone.
Use a sticky tape at the bottom of the GPS receiver to mount the GPS 
receiver on a location with a clear view to the sky, for example, the 
upper side of a dashboard. Mount the GPS receiver so that its upper side 
points to the sky.
When the GPS receiver is mounted, plug it to the GPS receiver connector 
on the hands-free unit. See Hands-free unit HF-20 p. 23.
For information on using the navigation software, see the user guide for 
the Nokia Navigation Pack LD-2.
