My new car, as of about 3 months ago, has, it seems, connections for everything. I've been taking advantage of SSD Chip slot with about 5 Gigs of albums I have purchased over the years. It is set on random and I totally love it.
I could, and probably will at some point, put the SSD Chip in my phone and Bluetooth that to the car's stereo. That way the music can go with me wherever I take my phone.
