IceLink - Battery Rundown Problems? Myth?

[bigjdtemp]

First, as a soon-to-be X5 owner, I'd like to thank everyone on this board for their contributions to the forum! You have all given me a true X5 education and answered countless questions of mine without me ever yet posting.

I do have one remaining question, however. I am planning on implementing the IceLink system on an '05 with the premium sound system and navigation.

Somewhere (not on this forum) I read that some users experienced problems with IceLink (well, any IPod connector I assume) causing battery run-down issues. Basically, the theory is that the IPod being constantly charged by IceLink will cause the memory feature of the battery to eventually prevent full-charges. (I thought the "memory" problem didn't even exist on newer batteries, but apparently it does, just not to such an extent as in the past.)

Still, this sounds suspicious as I assume IceLink would bypass battery drain all together and simply use DC power.

Any thoughts or experience with this?

Also, if anyone has any thoughts on how IPod encoded files (AAC, etc.) sound on the premium sound system versus CD or pure WAV files, I'd be very interested in this as well.

Thanks!
