If I wanna play the radio.. and switch it up once to power up the car just for the radio will it drain my battery dramatically.. I know other cars have like a one two click just for issues like that.. but this car just seems to click up once... Not shure if I'm explaining my self right.

 

You don't need to turn the key at all to play the radio. Just turn it on. If it was on when you turned off the car so the button is out, push the button back in, then push it again and it will turn on.

 

But will it drain my battery??

 

Eventually, but you could run that radio for hours before you put a real dent in your battery's charge.
