I have both xm and sirius and have adapters for either in both my vehicles. I was on travel and my wife decided to take the xm out of my car to use in hers because she wanted to listen to "Oprah" and she used the wrong adapter (sirius 12 Vdc). Obviously the Xm reciever didnt' appreciate this (6 Vdc input) and when I push the power button it starts up to the XM2GO page, flickers a little bit, goes to a blank white screen and then flicks over to "battery charging". When out of the charger it won't turn on at all. I am an electronics technician, so if it's dooable I'd like to fix it (any advice, direction would be appreciated).
Sorry to say, but this unit is toasted.. I have seen this same problem several times when people will cut the end off of their car adapter to wire it in permanently - only problem being, is the end they cut off holds the voltage reducing board, so they also send 12v into them, frying them and displaying the same exact symptoms.
the XM2GO needs to be sent back to the manufacturer for an exchange if under warranty.
There is not a readily available schematic for the XM 2 go..However, even if we did have one to look at, the circuitry inside that unit is so small, is ALL discreet surface mount components, and processor controlled - what I meant to say is this is basically an unfixable unit. They are built as disposables - it would cost more in labor and parts than it would just to replace the unit.

I would get a new main board for it. You probably fried one of the circuits.
try to find one on ebay
Shes probably fried.
Sorry
I thinkb the cirucit is blown u have to repalced it.
Where to start.... well take the case apart and look for the burnt components and replace them.... i would suggest buying a replacement as a good repair is not likely. there is one thing you could try... replace the battery... tho i do suspect it is fried

Don't really mean to be the bearer of bad news... but twice the voltage isn't good.
So the device got double the recommened voltage, a bit of a overdose. Well, Open it up and inspect the battery and its connectors. see if anything is burned.
It definitely wont be a easy repair, have a look inside.
Outside of warranty I suppose?
Yes the high voltage adapter has obviously damaged the board
you may not be getting enough power to the base because of a bad components l
connection between the base and the receiver, and it won't power
up because it has no battery charge. Try plugging the AC power adapter
directly into the bottom of the receiver . Push
the adapter plug toward the back of the receiver to see if the + sign
on the battery on the top right of the screen shows that it is now
receiving power and charging. Alternatively, with the receiver in the
base, try pulling the top of the reciever toward you to tilt the
receiver forward on the pins to see if it starts charging.

I guess I didn't post the question correctly. I'm well aware that the unit was damaged by plugging a 12 VDC power supply into the 6 VDC input. I was hoping to get a technical answer i.e. remove power protect diode at input (schematic description) and replace with (part number) etc., or if there isn't anyone who can answer how to fix it, maybe there is a way to transfer the radio i.d. to another unit (switch ROMs) etc. ( This is a DELPHI XM2GO SA10113 unit )Thanks
I opened the unit and checked for obvious damage and did not see any. I was hoping for a link to a schematic in order to troubleshoot. Specifically I would like to know if there is an over voltage protection circuit on the DC input to the device. Again, it will only power on (as described in the original post) when in the cradle. The battery will not power the device at all. Thanks
