I regularly use Zipcars around Atlanta. They have a mix of Ford Escape and Focus, Mazda, Honda, BMW, Mercedes, Subaru. I get to try out the Bluetooth connectivity in all of them. I've never had an issue with the Ford or Mazda models, they work great and once paired, as soon as I get back into the car and start it, the Bluetooth connection is ready to stream music, all call functions, etc. The BMW, Mercedes, and Subaru work nicely, as well, though it amazes me that BMW puts Bluetooth into a $40K+ vehicle standard, but to use audio streaming you'd have to pay extra (which Zipcar doesn't). The cars that just have completely crappy Bluetooth systems is Honda. I have yet to find a Honda vehicle that will reliably connect with Bluetooth on either my LG V10 or my HTC One M8. They refuse to pair, giving various errors or pairing but not actually working. Maybe Honda makes their systems only work with Apple products (a friend's iPhone pairs and works with them) but they don't advertise as being Apple-only, and Bluetooth should work on any system. So, now I avoid using any Honda in Zipcar's inventory.
