to run the newest (2009) navigation disc. My original disc works as it is intended too. With this being the case, will the newest version work on my car, which is a 2004 CTS-V? I spoke with the rep at Cadillac and she assured me that it should, but I have heard about the "stuck in Michigan" and possible firm ware issues. I would like your opinions before I drop the money on a new disc. Thanks in advance.
