Kenwood just announced last week its EZ900HDS, which is a tour de force of integration: it has AM/FM, HD, and Sirius built in. No external modules as far as I can tell. It's $799 list or about $600 street, which is a tidy price for something with that much integration. The CD player handles MP3 and WMA, of course. The street price drops by $250 for a similar unit without HD Radio.
