Not sure, but do you BOSE adapter for that RNSE? Not sure if this will fix it, but if you don't have this cable, this will be an easy fix for you. The other thing you can do is put your original radio back in to see if the issue disappears. Another post on here stated that the ground cable from the adapter may not be a good connection or large enough to handle it.

Good luck.
