We know the Rio portable protocol intimately and currently have no plans to apply it to the car player. To do so would drastically reduce the functionality of the product. That isn't a slur on the protocol - it was designed for very different products.

Right now I think the Java download tool is a good solution for the Mac, however we are still very open to developing a specific Mac version. At the moment the demand is very small however I would expect this may change as we sell more products.
