So I’ve driven cars by lots of manufacturers from all over the world.
So here’s a list of manufacturers that tend to include Bluetooth connectivity:
Ford: Yes – Sync connects to my Android phone
Mazda: Yes – no issues connecting
Toyota: All the vehicles I’v driven have full bluetooth
Honda: I’ve driven one Honda vehicle and no bluetooth.
Dodge: The Avenger has NO bluetooth
GM: No bluetooth
Volkswagen: No bluetooth
BMW: No bluetooth
Spewing Truth in the face of Lies 
How old were these cars?? I have a 2006 BMW and it has bluetooth.
They are all recent vintage vehicles – as in 2012 to 2014.
Oh and I think I might have figured out how to get around it in cars that don’t have bluetooth but do have an aux jack. I picked up a Jumbl bluetooth adapter. It plugs into my headphones but the thought hit me, I could plug this into the aux input jack and the audio would pipe through there. Sweet.
