12V feed for TV

Does anybody know if it is possible to get a 12v feed that stays on for 15 mins or so after the ignition has been switched off? Basically a 12v that goes off when the car system shuts down.
I've had a tv/dvd installed for a while, but the kids get really fed up whenever the ignition goes off, and switched the tv off, I believe it's possible to have a feed that stays on for a set period after ignition switch off, but don't know where this feed is located.
Just wondered if anybody can help.

The is a modification you can do to bridge the 12v Switched to Permanent in the fuse box. Meaning ALL the sockets stay live till to run the Battrey flat with Hannah Montana or Bob the Builder

I don't really want the 12v feed to be permanently live, just live when the car is open.
Is it possible to get a 12v feed from the wake on open signal?

Three options then, the one I linked to, or a seperate LIVE feed from the battrey or Aux battrey, or leave the darn keys in Laughing

You can use the infotainment relay supply, which will be live whilst the radio is switched on.

Easiest way is to use a piggy-back on fuse 58.

I have an inteligent PSU in the carpc I built. THis would shut down in 3 ways IIRC. When ign was turned off, When told to do so and after 15 mins or so.
Can't remember what it was called though, but it's about 2" wide, 5" long and about 1/2" tall

Like the man says Thumbs Up I think TFC has also posted some instructions on how to do what you need.
