my new nav unit can store mp3s ... but i havnt downloaded anything since the days of stealing Napster. My car has a cassette player so i figure i can dl some music on my nav and play them through the cassette with an adapter... Is this a sound idea? If so .. I want an easy site to download music....i guess you pay like 15 bucks a month or something? any info appreciated. i tryed those torrent sites.. i had alot of trouble with them... to hard for me to figure out so think simple.
