This was purchased new about a year ago and was working when recently removed from my car (2000 Saab 9-3).
I still have the printed instruction/operation manual.
$200 (includes shipping via FedEx in the US)

Full disclosure: I discovered while away for nearly a month that the AudioTroll draws power even when the car is off. I had my mechanic check things out after I jump-started the car, and he told me it was a slight drain "80 m/s", but my battery was completely drained after a month and required replacement.
I'd recommend pulling the radio fuse or disconnecting the battery if your car sits without driving for longer than a week. Because I don't drive very often and seldom take long trips in my car, the Audio Troll is not so useful to be worth the extra effort.
