Hi all, I have been using USAspec interface more than two years with battery draining issue. I just wanted to let you know one funny thing happened couple days ago. My 2004 H2 audio is NAV/BOSE system.

Since the interface installation, the way I use the interface is to select XM in BAND button then it produces iPod music thru the radio. Couple days ago BAND button stop displaying XM selection. I thought interface finally died. But as long as iPod screen goes it displays something like "GM ok to disconnect" which is quite normal behavior. So I wonder interface is still alive. But I lost the way to select XM to connect iPod music....

Today, I played with other radio buttons and happened to press CD button. Suddenly iPod music started. Now the radio recognized interface as CDX!!

I have no idea why this happened. But iPod music is back and at least I am happy with that fact. Just wondering if anyone else had this kind of experience
