What's this?

Couple of things I've noticed with the car:

I'm guessing this isn't normal. There's a wire coming out from the headlining by the rear mirror. The end has a mobile phone/sat nav attachment.

Also, regarding the trip computer, when I press A or B it just says 'route initialisation'

After market dash cam would be my bet.

Sounds about right
