12Volt-Travel has teamed up with Panasonic and Delphi who's AM/FM CD player stereos and cassette stereos are in most semi trucks and tractors. 12 volt travel supplies truckers and tractor owners with new original equipment stereos at just a fraction of what you'd expect to pay at a dealership. In most cases the installation of OEM equipment in semi trucks and tractors is relatively simple and is often as easy as removing the old stereo plugging in the new stereo and sliding it in to the stereo housing cage.
