There's your problem. It is that Apple believes that they do not need to comply with the actual standard. They prefer to do their own implementation and rely on their market share and rabid fan base to point the finger at others. If their products "just work," then it must be somebody else's fault, right? My guess is that this older unit just didn't get updated when Apple decided to go screwing with a system that worked just fine.
The hands free profile has been a standard for several years. My wife's 2006 Acura requires it for full compatibility, and when we bought it you actually had to look to find a phone that would work right. Some tended to work (Motorola, Blackberry), others not (Samsung, LG). Now, most new phones support the hands free profiles, and even previous iPhone generations supported it.
That it used to work, works fine with most other phones, and now does not means that the problem is on Apple's end. Maybe they'll patch their system, but I wouldn't hold my breath.
