when I got my motorhome it had a single stereo. I've taken it out and fitted a pioneer Avh 3800 double din with app use connecting iPhone.
The DAB and Bluetooth is working great but I cant use NAVMii because it won't allow me to enter a destination. It also comes up with message saying I can't use satnav while driving. I'm sitting still with ignition on and handbrake both on. Am I missing a wire to handbrake or is it something else. Also I don't know what the grey plug in is for.

Can anyone help
