Installation installing in 95 lincoln town car with no external antenna or cable, does the PANASONIC CQ-C3303U have internal antenna capability? and what is the blue and white wire for?

The blue and white wire is for the powered antenna, or signal remote wire for amp is also ran off that wire. as far as internal ant. cap you would have to check with panasonic about the add-on from factory though it does not. you should have a powered antenna or antenna in the windshield on the vehicle unless someone has changed the windshield for the cheaper model or removed the external antenna. which in that case you will need to add an antenna, can be bought at local electronics store or stereo shop. hope this help solves problem let me know if you have any more questions.
