Indeed, OEM does look the best. I have been looking at the DICE mediabridge as well. I may just get that for the time being. Eventually, I'll move up to either an OEM retrofit or Dynavin. Right now my X5 is experiencing some problems that may result in having to go in for warranty coverage work. Kind of bummed out about may not being able to drive anywhere this 4-Day weekend (in my car at least.)
I was looking forward to taking a little road trip through the mountains.
