The radio / nav system in our 2004 ES330 is woefully out of date. We just ordered what we hope will be an updated version of the map CD. But beyond that, it lacks USB connectivity and though one button is labeled AM/SAT, assuming the SAT means Sirus, that does not work.
Has anyone upgraded the premium system to something more current? Some of the aftermarket units I've seen available, though perhaps an improvement, fall short. None seem to have Sirus satellite capability, for example.
So, I'm looking for good recommendations.
Thanks,
