having problems with my car dvd

So today I installed a indash dvd player with screen in a 2001 tundra and everything works just fine, but when I insert a dvd movie the stereo tells me "insert Password" and the manual doesn't say anything about passwords or anything like that..im frustrated and have no Idea whats going on

ok, I just called the company and they told me to take it back and the problem is a software issue that they're having... fewf I thought It was my mistake

Nice of the company to do that, hope the replacement doesn't fall to the same malady.
