If you purchased a RA3 or RA4 for a 2017 Jeep Cherokee and your original radio has the volume knob on the radio, and not on the dash bezel below the radio screen, this radio will not currently work with your vehicle.
We have posted this to our site to help keep anyone from purchasing this unit in error.
We are working on a solution and should have something ready around summer of 2017.
For now we recommend returning the unit for a full refund and checking back with us in the summer.
Thank you, and sorry for any inconvenience this may have caused.
