I purchased the Blitzsafe unit for an iPod several months ago. Since then, I have replaced it a few times, the latest with the new version that allows XM. The reason for the exchanges is that the CD/Aux button will not always switch to CD-C (goes to XM1 or XM2 only). This latest variation of the unit does the same thing, although switches to CD-C a little more regularly than previous ones.

Does this happen to anyone else? I have been unable to find a consistent pattern that causes this error to occur - has anyone else? Is there a way to prevent this? When the unit allows the proper switching, it works great (get iPod, XM1 and XM2 clear as a bell).
