I put a dual in dash dvd player from best buy in my truck, I had to buy an interface for it to make it work, I got this from wal-mart like $40 I think for the interface. Now when its cold out when I start the truck the dvd/cd player will only stay on for about 3 seconds then shuts off.:mad: If I just turn the key to run, without it running, or accessory it will stay on until I start the truck.:wtf1: Then if I run it for a while, without it working, shut the truck off and start it again it will work.
Any ideas?

Anyone else used the interface from walmart? Im pretty sure the interface is the problem and not the dvd/cd player.
