I just have the single cd changer, I have seen one on ebay that allows you to plug a blue tooth adapter in for hands free I admit I miss hands free.One last thing on james utube video the screen of his car shows disc number as well as track number,because mine only has a single cd p-layer I only see track number I hope my screen will show the disc number as well
It kinda fools it into thinking you have a cd multichanger as it sees the mp3 player as one and opens the next folder/album as next disc.
