I've just bought a second hand 2008 Toyota Yaris YRS that has a CD Stacker/Radio/Bluetooth system in it. It looks like it's Toyota issue but it has no brand on it and it's not the same stereo as in the manual so I've no idea how to operate it. I've worked out everything except the bluetooth. When I try to connect my iphone the mobile finds the hands free but keeps saying that its unpaired. I read that I need a pass key but I didn't get one when I bought the car. Is there anywhere you can find or purchase additional pass keys? and can someone please tell me how I can get the bluetooth to operate. Thank you.
