CD changer or the AC is running the battery down.

[just-in]

Hi All,

1.Can the CD changer run the battery down when the car is off?

Or can the AC be the real culprit?

Because i still have this problem that my car is ruining the battery down but only when it is not in use.



2.I have now got on my x5 the TV.

Now I would like to install a camera for reversing but how can I choose, I can buy on ebay for as little as 21pounds UK pounds.

But it is from Hong Kong and dos not seem to have a make, have a look and any one thinks I should not buy this let me know, any one who can tell me a good make, and not too expensive let me know.
I live in Europe so must be able to get here.
