Ok, I have a 99 TL with the single cd player, my brother has the 00 model TL and he gave me the 6 disc changer that go's into the trunk. I did my search on here to see if it would work, I looked on the back of my radio to see if it had the aux/ hook up on the back and it do, so I hooked the cd changer up and it has power cause the eject works and you can hear the changer change a disc, but the problem is that I cann't find how to connect to the 6 disc changer from the radio and I pressed the cd button twice and nothing happened so if you have the solution to these problem please free to lmk Thanks....
