When receiving a call the 10-digit number is SOMETIMES displayed, and sometimes it states UNKNOWN even though the caller exists in the phonebook.

The Garmin Nuvi does not have a FM transmitter but comes with an integrated GTM 20 FM traffic receiver designed to receive alerts about traffic tie-ups and road construction that might lie ahead on your route.
