Gps audio

Hi, im doing a project whereby im using arduino and a parallax gps receiver. I only want the arduino to have an audio output. how do i go about programming this?

What has the audio output got to do with GPS?
What sort of "audio"?

Clicks?
Beeps?
Simple tunes?
MP3?
5.1 DTS?

Pffff. 7.1 DTS MA at the least

ouh wad i meant was that the gps information is to be given out by using only audio, not using lcd display

In morse?
In speech?

in speech, i want the arduino to say out the information of the gps

You're going to need an add-on device, like a SpeakJet.
Google gives lots of hits.
