Constant power to stereo
I have fitted a double DIN aftermarket DVD/GPS system.
The only problem is I have switched power which only comes on when the ignition is on. I do not know how to power the stereo direct from the battery. Every time I turn the car off, the radio presets disappera nd i have to re tune stations and reset my GPS.
Can anyone advise how to get constant power to the stereo?
Will this effect battery life?
Thanks
