I am going to install a aftermarket single din pioneer to my 2004 acura TL, I found a guy who makes kits online. The kit comes with the frame, brackets, wiring harness, and sub harness. With the Acura TL do I also need an antenna adaptor? Or is that not necessary with this car.

 

No antenna adapter necessary. If your new radio has OEM steering wheel control input, then you also might want to purchase an Axxess Interface ASWC-1 (steering wheel control interface).
