I'm replacing the 430N RHB radio in my 2014 JK 2 door Rubicon with a Pioneer AVIC W8400NEX, when I turn on the radio, go to the navigation screen I get a gps antenna error message that says to go see the dealer. If I leave the radio on and unplug the gps antenna and plug it back in, it seems to work, but when I turn the Jeep off and back on, I get the same antenna error message. I'm using the oem factory gps antenna with an idatalink Maestro NAV2 adapter. Any idea what's going on? Should I remove the factory gps antenna and use an aftermarket? Which aftermarket antenna would be good?
