I have an XMD1000 that was hooked to a head unit. It's been on the shelf for a year and I found the subscription was still active so i made a serial cable and hooked it up to COM1 on my computer. it seems everything is working as I get my channel list and I tested it w XMTest, SatAmp and RR. The problem is no audio out. it worked fine on the head unit before I pulled it out.
Any ideas on how to wake this thing up?
