All my cars you change a fuse to make the 12v DC charger always be on. Can we do that on the M6?

As far as I know the answer is "No". My 3 series used to keep the cigarette lighter "hot" even when off but when I got my M5 4 years ago I was told the M5 and M6 do not do this. It seems to also be true for my new M6 vert. Why ... who knows but ti seems stupid to me.

A simple option is to rewire the passenger footwell 12V receptacle with a hot 12v always on wire. Thats what I did and my BB and iPhone now have charging cables hidden under the trim exiting near the passenger seat for use (or in the glovebox if you prefer), for constant charging even when the car goes into hibernation

Just an idea and pretty easy to do by dropping the passenger footwell cover.

The answer is on page 93 of your owners manual.

"Cigarette lighter is only powered on when the engine is running or the ignition switch is in the On position."

In the olden days, it was considered a convenience (if not a necessity) to have a live cigarette lighter for lighting up when parked, such as when having a smoke after sex in the back seat. [Refer to fig. 1 below]

Today, as smoking has become more politically incorrect, and drive-in theaters have gone tits up, most lighter sockets are used for other purposes, or not used at all. So the manufacturers no longer provide it as a hot circuit.

BTW the new iPhone 4 cradle charges with the car off. Don't know if the other cradles do.

Also, you'd need to get marginally creative with the back seat in an M6.

The back seat ski pass-thru can be useful for certain orientations.
