Hi all. I have a 2018 Journey SXT that i bought used. It has the 8.4 setup with XM, no nav no bluetooth. I know what to do to add navigation but i want to do hands free. I cant find anything when it comes to the journey and hands free except for the crappy aftermarkets. I can find the bluetooth module, steering wheel controls but cant find the wiring. Does anyone know what other models that would be compatible? All i need is the wiring.
