Ok; I found a tuner here on the board. Should be here Thurs. What do I need to install it? I have a non-Bose TNR. Does it plug right in? Where? The small open plug on the back of the TNR? Is the wiring there? What do I need besides the tuner and antenna? Any help would be appreciated.

I have the Bose system, but I needed the tuner XMD1000 and the adapter XMDGM100 with wiring harness.

The harness plugs into the radio wiring and adapter, then run patch cable to the tuner.
