so id need the interface box to connect it to my antenna and power
supply?


Yep, comes with it, Not much in there, just power, ext speaker switching,
filter network and box. that part is sold as a spare from Cobra so the
handheld unit can be transferred between different vehicles.

'Bout 28 bucks. I bought one off E-bay for cheaper when I was using one of
these.
