@ codeman71 Thanks for your post, it's great to hear that those who design and work on the system read this forum. I'm sure it is not easy to "please everyone". Never mind having to deal with an ever changing technical environment on an ongoing basis.
You may wish to also read my request (rather long post) for some technical documentation in the threat http://www.cadillacforums.com/forums...-problems.html which, while not easy in every case, would assist both customers and GM personnel, be it at dealers or at Customer Support, as I found out that when asking questions at CDN Customer Support and at my dealer, regarding SD cards they didn't even know the various types available, never mind being able to tell me what is supported by the XTS. And based on various threats people had problems and there should be no need for "trial and error" by customers. The same when I asked about some phone issues. (don't have my XTS Platinum yet - tentative built date Jan 11, nor do I presently own a mobile phone but am in the process of buying one - of course I like a new model but one which works with CUE correctly)
