Squishor

I have a friend who just got given a new Mercedes by his father, and it has some sort of bluetooth-capable built in system on it. Mercedes wants an obscene amount of money for their special bluetooth phone but apparently the salesman hinted that some "ordinary" bluetooth phones are compatible with it.

Anyone know which ones??

My friend isn't even sure he can afford to pay for the insurance and registration for this thing, much less thousands of dollars for the phone.

Thanks!
