I purchased a the switch of Tom at EAS and it is nice to have the option to switch back to the CD but I have only done it a couple of times to be honest once was when I was going on holiday and had the I pod packed in hand luggage,I could have listerned to the radio instead but I did not have to. The other time was when I left the i pod at home in the Docking station.The other problem is when using the CD if you turn the ignition off goes back to CD1 track 1.
