Tim,
Note that this is a site that is primarily geared towards the BMW X5 and X3, so most of the expertise and information you will find here is associated with those vehicles.
You might want to try a Google search, such as this to find an interface that you are looking for. I think they are out there, you just need to determine which one works with your particular vehicle.
