2007 camry, upgrade to NAV or upgrade climate control

[weaselphd]

I have a 2007 camry with the standard climate control and standard CD radio 6 disk, with upgraded JBL system. my question is this i really would like to buy the NAVIGATION unit, its on ebay labled "07 Camry Navigation Unit with Radio Controls LKQ" and im just wondering if this is plug and play can i just swap them out? if not second question is can i swap out for the digital climate control with radio when i have the stnadard dial version?

thanks
