Older Infiniti. If the names on the quick list are easy to say, it might pick them up... but I have a lot of odd names that is has problems with. I considered renaming my contacts to single digit numbers or something equally simple, but... nah.
And at least before the most recent firmware upgrade (maybe still like this), it was bad about calling the wrong person without confirmation... so if it got it wrong, bam, you were in the middle of a call to somebody else. That stress was not worth it! I found myself watching the screen more in case it called the wrong person, which defeated the whole purpose of hands free.
