It would be cool if the Cheetah Mirror had a 12 volt powered plug able to accept V1 and other radar detector cords. A version of the Stealth Cord might be more practical, with Cheetah selling the special cord needed to plug your V1, Bel, etc. R.D. into the Cheetah.
Since you already have a 12v cord for the Cheetah you would not need another for your R.D., just the short connecting cord from the Cheetah to the R.D.
