I think I messed something up.
I have a 2004 Acura TL without Nav.
After upgrading the PXAMG unit to the 37e release/revision, I inadvertently plugged in the unit with the dipswitches on.
The unit didn't work, so I unplugged it, and waited 15 minutes.
Then, I did not reconnect the unit, but turned on the radio, and no XM.
Changing the radio mode completely bypasses the 2 XM channels/modes.( XM1 & XM2)
So i re-plugged the PXAMG unit and still no XM.
Now I am without XM as well as the ability to listen to my iPhone music. I have the 3G iPhone with version 3.0.1.
Prior to upgrading the PXAMG to 37e, I had no problms using this unit.
Any ideas on how to get my XM back and then the PXAMG unit working?

 

i'm assuming you switched the dipswitches back to off?

Press FM/AM a few times and then hit XM and very quickly rotate the tune knob till you see IPOD or AUX1/AUX2 and it should work.

If anything, you can disconnect your car battery for 30 minutes or so and reconnect it.

 

Yes, I did switch the dipswitches back to off.
I tried what you suggested, and it looks good/works now.
With this help, and help from AAMP tech support, it's back/working as normal now.
thanks. much appreciated.
