I have a 16.5 sport with 2.5l. It has the knob thing in it, and it doesn't remember when I leave my ipod connected and turn vehicle off. Also, it doesn't pick up my playlists(originally was at 3.5GB), and it only picks up library only(over 300 songs), and it keeps starting in alphabetical order with Adele(drive 5-10 minutes and 2 mile ride to work, and once I get to something I want to listen too I'm at work). I took the library out and all playlists and create one playlist. It still doesn't remember and it puts things in alphabetical order, so it's not in the order of the playlist. I have heard cracking noises on some files, and I went back and converted to the least amount of bps. I believe mine were at 256, and it is now at 128, so I haven't heard the noises since. If my son is on the phone watching a video, the sound isn't playing through the radio, and it actually mutes the phone. I bought the vehicle 2 weeks ago, and I'm figuring it might be me, but reading this thread has me thinking twice about it. I don't drive much, and vehicle currently has 300 miles on it(wife has driven it more than I have). Is anyone else experiencing these issues in a 16.5?
