Incorrect my friend ! A failsafe only guards against loss of signal, NOT loss of power !

Ive used a failsafe since the day I bought the car.

Well I don't know what kind of fail safe your using, but I don't want one of those!
I have a Futaba FP-T3PB PCM Radio with built in fail safe & when theres loss of power it stops the car dead in its tracks! I also have a JR radio on one of my other cars & I use an Ofna micro fail safe adapter & it does the very same thing as the Futaba!
So you might want to look into a new fail safe my friend..
