Navigation's GPS location freaking out...

[quackman]

I've had my car since summer of 2008. Recently, as in a couple of weeks ago, I started noticing that once in a while the car would no longer be able to realize where I was, and put my location back at my house or a random place for a minute-to-a-few-minutes, trying to figure out where i really was. Yesterday while i was on a drive for over a half hour, this was taken to the extreme: every few minutes the car would lose track of where I was and think i was back at my home address. It'd keep switching back and forth every few minutes between there and my actual location.

Has this happened to anyone else? Is there a way, if I ever were lost myself, to reset the system in hopes of its working fine again? I guess turning the car off and on again would help, but I'm wondering if there's a way to reset i-drive without turning the car off. Any idea what might be wrong with the car's GPS system, hopefully something they'd easily be able to fix next time i brought my car in for service?
