I installed a CB radio and antenna in my 2012 Wing this afternoon. The instructions are fairly straight forward and easy to follow. The biggest headache was gettting the seat bolts started. It took me almost as long to do that as it did to install everything.
After disconnecting the negative battery cable I was expecting to have to reset everything. The only thing I had to reset was the FM stations preset buttons. The clock and the XM must have memory because I didn't have to reset either one.
