My daughter took out a policy with the black box fitted. They failed to inform that this plugs into the 12volt port that already houses her dash cam. She wanted to cancel her policy. It was then we discovered they had her by the sort and curlys. She has to pay £10 for a double socket or to be charged £75 to return it and cancel. For youngests avoid this company . Having a dash cam is more peace of mind in my book.
