I have no problems pairing my Cat B15Q (Android 4.4.2) with my 2013 Toyota Auris over Bluetooth. However, it stops there. As soon as I try to use the connection (make a phone call, play music, access the internet), the Toyota complains with a non-descript error message.
I have been able to successfully connect a WinPC with the phone (incl. file transfer).
Does anybody know any tricks? I have tried the obvious ones: deleting the connection, re-pairing. To no avail. The car can use my wife's iPhone 6 over Bluetooth. I have contacted Cat, but they say the problem is with Toyota. When I see the long list of phones compatible with my car, I can only wonder why my phone isn't working and why the problem should be with Toyota?
