I purchased a new strereo with CD and IPOD connections and wish to install it myself in my 04 Explorer. How can I remove the old stereo?

Do you see the four small holes? You need a tool like these, you can get them at walmart. http://www.amazon.com/exec/obidos/search-handle-url/index=blended&field-keywords=ford%20radio%20removal%20tool&results-process=default&dispatch=search/ref=pd_sl_aw_tops-1_blended_35223616_2&results-process=default
