According to one embodiment, an electronic device, for example, a portable electronic device such as a cellular telephone, a portable navigation device, a personal digital assistant ("PDA"), or an MP3 player, includes a GPS receiver configured to receive GPS coordinates. The GPS coordinates are sent to a CPU that is configured to retrieve location-based information from, for example, a memory device or a cellular module in the electronic device. An FM transmitter module is configured to encode and transmit the location-based information as encoded text, for example encoded RDS text, to an FM receiver in a vehicle. The RDS text can then be displayed on a display panel of the FM receiver. In addition to the encoded RDS text, audio signals from the FM transmitter module can be transmitted to the FM receiver for broadcast by a speaker of the FM receiver contemporaneously with the display of the RDS text.
