2012 Solera "S" with 12 volt Jensen TV. As stated above - no headphone jack. I use an adapter like the one pictured above on the "Audio Output" RCA jacks (have to disconnect the plugs put in the jacks to connect to the dash radio). Then check setup menu on TV - turn speaker "off", set volume to "variable" (not sure of Jensen nomenclature or where in setup menu these options appear - memory says not in same menu section). Then turn up the volume to comfortable earphone volume. Works well on my unit.
