I chose this drive to its design and dimensions. Like others, I was extremely disappointed with 2 really huge flaws: - No memorizing the last used source for ignition (cd, tuner or USB): The unit always starts on the CD! - The sound is still recovering at a level frankly too loud when turned on, it does not memorize the last sound level. So we come to regret the good old rotary knob. Both defects are so prohibitive that I retracted me, I think they make the product unusable, despite his other qualities.
