I bought the new car radio/stereo unit, installed it, but there is a problem it wont stay on when i turn of my car. And it also loses preferences (volume, radio stations, etc)
Info about the connection from the car:
- Yellow wire - it is labeled "Battery" (on the car side), voltage is 12 when car is on, 0 when car is off. On the adapter that came with the unit, yellow wire comes with a 'thing' on it, like a bulb with the wire in the middle, don't know what it does. In the unit instructions/manual it says this wire is "Memory", whatever that means (probably always-on wire)
- Red wire - it is labeled "ACC" on (on the car side), voltage is always 12 volts, whether car is on or off.
So first i tried to reverse the wires, red goes to yellow place and yellow to red, didn't work, no difference at all, unit only works when car is on.
Now what i did is connect both (red and yellow) wires on the adapter to the red wire that comes out of the car, this effectively makes both yellow and red wire connected to the unit always at 12 volts. That seemed like it fixed the problem
So my question is, is this a good solution, or did a do something stupid and tomorrow when i go to my car i will find it not starting because my battery is dead?
(didn't really leave it like that, i disconnected the unit, just in case :D)
