I have an 03 SC430 and I am replacing the radio. Here are my questions.
1. My car has 2 antennas, what does each one do.
2. My car has 2 antenna jacks one normal size and one slightly smaller. Which one goes to the windshield and which one to the telescoping antenna in rear.
3. The original radio has 2 antenna inputs but the new radio only has 1 input which is what I call normal size. Will I get better reception by using both antennas and if so is there a Y adapter I can get to make that work.
Thanks
