Totally agree, the Bose stuff isn't really Bose. It's totally garbage. Got the whole lot in my garage. Removed after 3 month on my Z when new. Could get rid of it fast enough. Turn it up and it sounds like a duck farting under water.
If you only listen to the radio, why bother anyway.
My Zed is completely 'Bose'less... well some of it is still in place but not in use
