Hey guys, I have a 2004 grand prix with standard audio system. I want to know if there are any complications in putting in an in dash screen as well as would i be able to use a standard wire harness instead of using the harness to re-locate the radio. As per best buy, they informed me that i have to use the wire harness which costs 65$. I would like to know if i can use the harness that cost 20$. If that is possible!!


Thanks!
