I want to convert the installed 30-Pin IPod Connector in my 2008 Lexus RX-350 to a 3.5mm Stereo Mini Jack Cable. Something simple that I do not have to rip into the dash but plug into my glove compartment. I am okay with losoing the IPO capability. Am also okay not having charging or remote selection capability from the dash. Just want to be able to play my MP3 through the existing 30 pin connector. Most connectors on line state theirs will not work on Lexus automobiles. HELP!
