So my antenna base works, but the gasket is shot and water is leaking inside the car. I have the Navigation/ Sirius option. But I don't have these options, I only have bluetooth. I don't want to pay 160.00 for a new one and wanted to know if I can just use the base model. The 2 ports on the base never had the wires plugged into it, only the pink and black wires were connected and everything seemed to work fine.

Original antenna base

Water damage

The wires were never plugged into these 2 ports and the radio worked fine

Base Model

 

I could be wrong, I think that base supports Sat and AM. I believe FM antenna is located somewhere in a window.
