Anyway to bypass the gmos-04 adapter for 05 yukon

[ANT LAY 4]

So I just bought a 05 yukon with factory head unit and bose system and I ordered a kenwood kdc-x794 to replace headunit then pulled out old h/u and its got a couple plug ins for wire harness so I googled it and found out I needed the "gmos-04" adapter that cost around 100 bucks that is supposed to keep onstar ability and factory chimes, is there anyway I can bypass the gmos adapter to install the new h/u?

If I can't bypass it where is best place to get one?
