ok, has anybody swapped out for this particlar OEM unit, it it possible to do in an 04??

 

WOW i have never seen an OEM part like this for a monte. This was an option....really?

 

I believe the Warner Bros. Venture Van had this option. I'm VERY sure that Impala/Monte Carlo did NOT. However, that doesn't mean it won't fit. I would ask for pictures of the whole dash so you can verify that it is in a Monte Carlo (If they have a unit installed). '04-'05 Tahoes had a special order nav system, I think...I would be weary of buying it just in case it doesn't fit. Compare the brackets on the nav to the ones on your radio and see if they are the same. Like the seller said in the description, I'd check with my dealer first. That's a lot of money to spend and have it not fit. Good luck and keep us updated!
