OEM CD Player upgrade

[mispoken]

Hello,

I have an 07' aveo5 base model with an AM/FM tuner only. I would like to upgrade to an OEM CD Player for ease of installation. I searched this forum a bit, and it sounds like it may or may not be "plug and play" like I'm looking for. These are the OEMs I've found on ebay:

The confusion for me is regarding the plug types. If I buy an 07' OEM CD Player for an 07' Aveo5 SVM, will it the existing harness fit the "new" OEM replacement CD Player? If not is it as simple as buying a new harness that fits the CD player, cutting off the old one and splicing in the new harness?

Thanks!
