Need help upgrading factory radio

Hello fellow Lexus frat members. I'm new to this site and am having some problems with my 2002 GS300. I'm looking to upgrade my factory radio with a Jensen VM9512 and NAV101, but no one offers a wire harness. I took it to one stereo place and they got everything to work but sound. Apparently they can't find the "factory amp turn on wire". Anyone have any suggestion on what they did???

i upgraded mine to pioneer. it was fine. i needed an aftermarket amp for my sub. but everything else was plug and play. i wouldnt really use jensen on a lexus tho... but other wise it should be a simple installation.

amp turn on White/Blue wire just connect the turn on wire from the AM headunit to the white and blue, most AM radios AMP and ANT turn on's should be Blue. Hope that helps
