A:AnswerI found not more than about 4-5 hours on set of 8 batteries. And if you don’t use the batteries and just leave them in unit, they die as well. Very poor design.
A:AnswerYou have to call to active the Unit , with Sirius XM. They can get that Info for you,as they did for Me!! Or your car Vin Number is usually on your door jam or on your car title. You will need to have the signal adapter where the say to place it to help get this set up properly??
