Hi all, I have had programmable memory direct selection button no. 4 assigned to play CD. Before my last visit to the dealer for the iDrive software update, I was able to switch my entertainment system to CD by pressing no. 4 and resume the music from the last played position. After I received my X, all the button assignments were gone, probably they had to disconnect the battery for software update, so I had to re-program my direct selection buttons, now the button programmed for CD starts playing from the beginning of the first track on the disc. I don't know why it doesn't start from the last played position. I am using the procedure explained on page 23 of the owners manual to program these buttons. Am I missing any step..??

Thanks...
