Hello first post here. I have a 2018 defender xmr and I am having a problem where my radio will turn on when key is in the on position only. If I play the radio with the key in the on position and start the Sxs it turns off and won’t come back on unless I shut the bike off and turn the key back to the on position. It won’t play with the key off either. My voltage is good (13.8+) I have a new factory upgrade battery as well as a new 2nd battery. Any help would be greatly appreciated.
