Voice Command button on steering wheel

When using voice command button on steering wheel via bluetooth handsfree on my 2010 Tundra, it won`t recognize command or it will advance to something different (ex: "main menu" > "redial or call cannot be placed"). Then it will disconnect for no apparent reason...maybe a loose wiring? Any wiring diagrams out there or anyone with similar trouble?

 

If none of the commands work, and did prior, I'd check for updates and force a hard reboot.

Disconnect negative terminal. Get in drivers seat and pump the breaks 10 times or so (The idea is to drain any residual juice in the electrical system) . Reconnect battery.

Check functionality.

As goofy as this seems..

Its worked on other Toyotas (after changing a battery)
Its free.

Other than that... A ten year old head unit.... Eh....
