Any thoughts on troubleshooting a SUM issue? Says that the communications are down with it.

Is it there all the time or once in awhile? When you reset it does it come back?

I found it. Previous owner hooked his imiv up to the damn fuse for the SUM. When I removed the wiring for that the fuse for the SUM came with it.

Game over
