I purchased a 2012 Dodge Journey SE. Well-equipped vehicle, but I realized it only has AM/FM radio in the Uconnect 4.3 radio that is installed. The deal to take it off the lot was too good, so I bought it. I have two years of Sirius and would like to get it in the vehicle. Is there something I can get that will let me add Sirius to the built-in radio? I know they have the 4.3S option - the hardware doesn't appear any different. Any help is appreciated. If I have to go with a portable radio and plug it in the 3.5mm jack, I will, but I'd rather go built-in.
