Hey all, I tried searching the forum but to no avail. I'm installing a Pioneer AVH-P3400Bh (double din touch screen dvd player/bluetooth etc..) into my wife's 2007 Grand Prix. It's a base model but it does have the on star. I got the good wiring harness and have it all wired up and ready to go.

The problem I'm facing is if I need a dash kit or not. I called a local stereo shop and they said "a double din won't fit dude, that's a 1 1/2 din car". The guy's an idiot. I tried to find a dash kit at wal-mart and best buy... but to no avail. Do I REALLY need one? The past two installs I did were in 99's (a GP and a dodge ram) that were both single din easy peasy. This one's got me all confused.

Thanks!
