Help auto on/off when AC power in connected/disconnected app? Please help!


Hey guys, is there an app to where it puts the phone into standby automatically or shuts it down upon losing AC power and turns it on or brings it out of standby upon gaining AC power?

I have a garminfone running android 2.1 and I just want to use it as a standalone GPS that turns off/on or goes in/out of standby when the car turns off or on. I have it permanently connected to the car's power source too. My old garmin nuvi did this, however and I was wondering if there's an app that can provide me with this kind of service. Thank for all the help!
