If HD came as optional equipment, then it certainly cost you. I believe even with Sync, and the optional nav system, HD Radio is still an option. If it was included as standard in navigation systems, it still costs you. There are costs to install it, plus iNiquity's royalty fees. All of these costs are hidden in the final price of these vehicles. This is why none of the automakers are offering stand-alone HD radios, including Ford. BMW and Volvo tried it, and all it got them were Technical Service Bulletins, and angry customers that demanded replacement radios. When HD Radio is burried with other devices, such as nav systems, dealers are far less likely to replace the whole unit, due to HD Radio's flaws, and makes it easier to blow off their customers. What is good news is that MSN Direct just shut down their traffic services, as they had partnered with Clear Channel HD Radio back in 2007. Also, Garmin just layed off 1,300 people from their traffic services, and they just started using HD Radio as the delivery platform. These nav systems are being killed by such smartphone apps as Google Maps and Aha.
