HD update: (Actually was done a while ago, but I forgot to include it)
As far as the delay when loading, I have fixed that. I messed around to see where the read was stored, and it is in the USB adapter, but the device must remain on.
I played around with turing stuff off and on, and figured out the IP-BUS cable from the HU has a 12v remote wire to a relay in the adapter. So by cutting the IP BUS cable, and locating the 12v remote wire, I was able to direcetly wire it to a 12v source, with a switch that I can control.
Now it stays on if I turn the ignition off and then to acc. What this means is that playback resumes (where it left off) in the amount of time a CD would take (basically instantly). Then if I am not going to be listening to it for a while, I flip the switch off, and turn it back on when I start my durango in the morning.
