Been looking at new cars because my little 4 banger Rav4 just doesn't hack it on the highway going quickly around those big UPS trucks, etc. Other than that it's been a great performer, but after 6 years and 101,000 it's time and I'm ready to upgrade to a new car with hands free Bluetooth technology. I don't have a smartphone so I'm not real savy about them. My grandson uses a Droid because he can transfer music easier he says, than his sister who uses a lot of itunes on her iPhone and has to go through a lot of trouble to move music around. I'm going to make the move to iPhone or Droid and transferring our music to them and playing the music through a new car system easily is what I'm asking? Would there be any difference between the two phones? Anyone with knowledge in that area care to comment please.
