have an 05 maxxus with stereo and floating remote that controls stereo and pumps. stereo is awesome; remote works well except the buttons for pumps are not controlling the right pumps. my dealer (Gold Coast Spa in Charlotte, NC) has been great . has been out multiple times to try to reprogram and change wiring harness per sundance direction; however nothing has corrected issue. seems to me like a software program issue. sundance now has their engineering dept. looking at this issue. has anyone out there run into this problem? if so, did you find fix. other than this, the spa is great.
