ok I just got done installing the second interface from Logjam and guess what--it still didnt work. I called Soundgate tech dept,and after 3 or 4 different reset procedures it finally worked. Here is what I came up with--The soundgate interface should have the power hooked up last. Get everything installed all wires connected and then lastly hook up the power. It may also take disconnecting the power from the xm 910 at the same time. The reason I say this is because my battery went dead after install(listening to xm with interior lights on and key on etc..) and I lost the display again. The only way I could get it back was to disconnect power from interface and xm tuner and then hooking them back up pluging in the interface last. Ihope this helps cause it would have saved me some headaches last week if I had known then.
