The only car manufacturer I know of that is promoting HD radio is BMW. I
have heard the BMW commercials on AM radio as my source but I don't know
if it is an option or standard or any other details. Could be just
promotional BS. I'm not interested enough to follow up on it. I already
waisted my time on the Samsung site looking for vaporware.

My X5 has HD. Third generation and marvelous. Takes FMs in HD to and beyond
the useful analog contour, and AMs on clean frequencies beyond the onset of
noise on analog. During the storms two weeks ago, I could get KNX HD for
news well into Riverside County, while the analog signal was unlistenable
due to the lightening and atmospherics.

Samsung does not promote the HD chip to consumers. It has certainly spent a
lot of time with iBiquity and its shareholders, though.

"Renowned Cambridge SoundWorks HD Radio Designer Explains HD Radio"

"HD Radio broadcasts require a consistent, stronger signal than analog
broadcasts... Below the minimum required signal le vel, the HD Radio
program switches back to the analog signal... There is a limit to how
far you can be from a transmitter and still receive an HD Radio
transmission. For flat land with no obstructions, this limit could be
as far away as 20-25 miles. For hilly terrain, the limit may drop to
10-15 miles. For the strongest signal within 20 miles of a radio
transmitter, the user should position the provided 30 inch dipole
antenna either horizontally or vertically along a wall or window."

"Questions About High Definition HD Radio"

Q: Why do I get drop-outs or silences on the HD2 Services?

A: This is a sign of marginal signal strength at your radio. It is
important to remember that the HD Radio multicast channels (HD2, HD3,
etc), unlike the HD1 channel, do not have an analog signal for the
radio to 'fall-back to' when digital reception is lost. So a listener
with marginal reception that is losing the digital signal will
experience periods of silence until the signal is regained.

This bring up another question of why they don't have indicators to show
you what is happening. I guess that would take all the fun out of it.
