HELP! Dead Nav/Radio with Hum

[Candlemuse]

I think you are taking the best option , by opening the console and checking the connections. I would also take out all the cables and connectors which came with the USASpec adapter , and connect the OEM connectors to the
head unit. Unless there is something visibly wrong with the cables or connectors.Otherwise the head unit should work. Just to update you I received the Peripheral, PXGM24 V2 today , and installed it. It works . It is probably too soon to say anything good or bad about it , because the USASpec adapter that I took out worked for couple of weeks before starting to cause problems.
But what was a major concern for me from day one was that the USASpec adapter displayed the XM 1 and XM2 before switching to CD changer input
to be used for the iPod. the reason I need 2 inputs is that I need an input
for the iPod and an Input for the satellite phone.
I hope to hear from you , to see how is every thing going with the problem.

I still have not run down the problem. I unplugged the cable from the Ipod adapter and the unit is still dead. My system functioned flawlessly for a year before this problem occured. It's going to be a week or so before I can get to tearing the truck apart. I have several trees down from the Ice Storm that I have to deal with in the near future. I'll post again when I open things up. I'm supprised that no one else has anything to add here. The forum is usually more help than this? Does anyone have any thoughts?

Candlemuse, I had the same problem with the USA-Spec. It worked great for about 3 weeks then my radio went dead. As soon as I unistalled it the radio worked fine. I sent USA-Spec between 4 and 5 emails and they never responded to any of them. I went out and purchased the GM-24 and I have had it installed for about 2 months now. It works great so far.

On the usaspec you need to get behind the radio unplug the usaspec harness from the radio, unplug the usaspec harness from the factory radio harness and plug the factory harness into the radio.
