JY-VQ131N4GN multiple issues
Hello, I'm having a few issues with my new JY-VQ131N4G.

1) Under BT, I cannot see available paired devices, so I can't really change to a different phone if I wanted to.

2) Steering wheel control seems hit and miss, forward button = reverse track, and reverse button = forward track.  The learning function under "Factory" doesn't seem to learn anything.

3) When I receive or placing a call, the MFD doesn't show the call information, and the steering wheel control cannot control any call function.

Any advice?
