Bro radio antenna is embedded in windscreen, as you can see a shaded wire net behind rear view mirror. Antenna wire (Black Coaxial wire) can however be accessed from Passenger side behind center pedestal i.e on the rear side of JVC player. If your wind screen is replaced at some point of time previously and was not replaced with genuine one then it would be difficult to find the antenna wire at the back side of the player.
What you can do is to buy a portable antenna with connector and attach it with your JVC player. I'll try if i could find some pictures for you for Antenna installation.
Hope it will help. Plz don't forget to join my website on Suzuki Liana
