I had a similar situation in a different vehicle. I went to Radio Shack and bought a cigarette lighter extension cord. It had a plug on one end and a female lighter socket on the other. I cut the wire and connected the female socket side directly into the 12v line under the dash. I then plugged the XM Radio power adapter into the extension socket and tucked it all behind the radio. Worked like a champ. This was a japanese car, and the aux power jacks go off with the key. In the Edge, they stay on all the time, so if you do this the power will always be on. They draw a tiny amount of current, but could have a negative impact on the life of the battery. In my prior company car (a Ford Freestar) I left the XM radio on all the time, and the OEM battery failed after one year. I don't know if this was the cause, but lead-acid batteries don't like to be drained down on a regular basis. Perhaps you could find a switched 12V line, and this wouldn't be an issue.

My 2008 Edge FWD has about 2800 miles. I was moving down the road and bumped the transmission into neutral. With my foot off the gas, the engine RPMs did NOT return to idle. Instead, the engine seemed to remain in gear, and the RPMs slowly dropped as the car slowed. If I tapped the gas (still in neutral), I could feel a small 'bump' in speed, as if the tranny had to be convinced to release. I'm not concerned about this, just curious. In every other car I've owned, placing the transmission in neutral allowed the engine RPMs to immediately return to idle. I'd be curious if anyone else has the same experience. Rick
