Hi all,

I'm having a electrical problem with my 03 R53 and I think it's something to do with the power from the radio and lights.

I wanted to know if you guys can turn on and hear music in your cars without the key in the ignition and switched on.

 

Yes.
If I get in my car without key in the ignition and push the radio power button, the radio will turn on and I can hear music.

 

Yep, that is a feature of the factory radio. No key needed...Press power & enjoy 20 minutes of music before it auto-shuts off.

 

I could have sworn it was a half-hour before it shut off, but I've never timed it.

 

no, 20 minutes

 

i think there's something wrong with my system though. the fan / vent stays on too.
