So, I started doing my research regarding this audio system and I got some questions :-
1. How do I get to know which music system I own? Some say its a rockford fosgate system but my car doesnt have that sticker to confirm that and since I dont run CD (Who does that in these days), I have no idea that do I have a 6 CD changer unit or a single CD unit.
2. Does this audio system works with the controls on the steering wheel?
3. Since this system comes with its own microphone and since my car already got bluetooth and mic to take calls, is there any way to use that same mic which is already in the car?
4. Is this thing even worth to upgrade??
I would appreciate a lot if anyone can help me out with this.
Cheers!
