I have just got a Sony headunit and I swapped it over with the original that was in my car. All was well, it was working brilliantly but then the following morning I went to start the car and the battery was dead.
I think I followed the instructions correctly and swapped the yellow lead and red lead around as it said so it only operates when the ignition is on.
Any idea why it drained my battery over night?? I know it is the radio that made the battery flat as it started perfectly before I put it in and the next morning nothing. Didn't leave the lights on or anything, i did check.
I've got it set up now so that the only power going to the radio is coming from the wire which is only live when the ignition is on. This is not ideal as no radio stations can be set and the CD is ejected everytime I start the car as all power to it is cut when the engine is turned off.
Someone please help!!!!!!!!!!!!!!

You could have drained it while using it after you installed it, did u try starting it after installation? It happened to me with my CDXMP70, the standard battery was due for a change.

I dont think i would have run it down. I only played a few tracks of a cd to make sure it was all working correctly. I've charged the battery up fully now and I'll have to test it and if it does drain my battery again i'll have to put up with not saving radio station, etc. I've got the Sony CDX MP40.

That is a good answer. It did beep to tell me that I left the front panel on when I turned the ignition off so I took it off and it still run the battery down.
