Great! I just scored a RA4 with nav from another 2016 cherokee out of a junk yard to upgrade my 5.0. I'm hoping it'll be plug n play. I just pulled my 5.0 out and see that I don't have the blue navigation connector so I too will need to purchase a nav antenna. I believe this is the part number? 5064350AA
Does the gps antenna install under the dash just below the windshield or does it have to be routed through to the roof?
