My 2007 XK has the standard stereo setup. What options, if any do I have to upgrade the stereo system? I've looked on in this forum and other places online and can't seem to find a solution other than going the ACM route. I asked a local dealer about updgrading the entire head unit with a Jaguar head unit and he siad he never heard of that being done. Any guidance/help/asistance would be appreciated.
